Automated oscilloscope calibration may represent an increase in productivity in many calibration labs. If it is manual, the job requires a skilled operator to spend a lot of time performing essentially repetitive tasks. Semi-automated or automated solutions can clearly solve this problem and free up skilled technicians to perform more valuable tasks.
Over the past decade, the oscilloscope of choice has evolved from a two-channel device to a more complex four-channel device. During the calibration of these devices, the calibration signal must be transferred from one channel to another. This can be achieved by physically moving the cables, but requires operator intervention. In high-performance devices, additional measurement uncertainty can be introduced when handling cables and connectors. Another option is to use a switching matrix to switch the signal, but this can also lead to other problems such as signal reflections, poor contacts, and channel differences, which ultimately have a significant impact on calibration uncertainty.
The Fluke Calibrations 9500B solves these challenges with its unique active head and provides truly fully automated calibration capabilities. With the 9500B, all the signals required to calibrate the oscilloscope are generated in an active signal head away from the calibrator mainframe. The active signal head connects directly to the oscilloscope input without the need for additional cables. All waveform control and switching actions are controlled by the host computer, but the waveform control and switching actions themselves are implemented inside the active signal head - that is, these signal waveforms are generated just a few millimeters away from the oscilloscope input and amplifier. Each 9500B head unit controls five active signal heads, providing all the signals needed to control and switch calibrate a 4-channel oscilloscope, including an external trigger signal, without the need for operator intervention or external switching of switches.
The final step in a fully automated calibration is the software. The 9500B Oscilloscope Calibrator can be used with the powerful IEEE-488 (GPIB)-based Met Cal Plus automated calibration management software. Met Cal not only automates calibration, but also records calibration results, manages calibration catalogs, and enables you to develop new oscilloscope calibration procedures. The software runs on Microsoft Windows and supports multi-user networking, enabling advanced features such as ISO 9000 compliant traceability, generation of customized certificates and reports, and advanced programming. The result of using Met Cal software is higher productivity, better calibration consistency, minimal human error, and reduced operator training requirements.

Oscilloscope technology and performance levels have changed dramatically in recent years, and the trend continues. Instruments that were considered cutting-edge devices just a few years ago may now be part of the Universal Arsenal. The challenge of maintaining the calibrators used to support these devices is to keep pace with this development. The Fluke 9500B provides the perfect upgrade solution. Now you can invest in the right 600 MHz oscilloscope calibration solution. When the workload changes, a well-performing device becomes even more important, at which point you can upgrade the performance to 11 ghz、3.2 GHz or even 6 GHz. If you need to use a device with good performance, you can always upgrade directly. If you don't need a fully automated solution for the time being, you can just use an active signal head first. When requirements change, active signal heads can be added until the level of automation and performance of the system fully meets the needs of your daily calibration oscilloscope. Only the Fluke 9500B Oscilloscope Calibration offers a solution to protect your investment in calibration equipment with its unique Active Head Technology.
At Fluke, we fully understand that we must focus on a high level of performance to maintain our position in the field of oscilloscope calibration. However, we also understand that not everyone needs high performance, at least not yet. To meet the needs of calibration labs, Fluke offers a range of 9500B products. Includes:
9500B 600, 600 MHz high-performance oscilloscope calibration solution.
9500B 1100, 1100 MHz high-performance oscilloscope calibration solution.
9500b/3200，3.2 GHz high-performance oscilloscope calibration solution.
We know that your needs are bound to change in the future, and buying a new device entirely to increase your performance levels isn't the way you want it to go. As a result, you can upgrade any of the models listed above to a higher level of performance at any time, and if you already have a 9500 calibrator, an upgrade option is available separately. We will do everything we can to ensure that future developments are also in line with this upgrade concept.
Four different active heads extend the upgrade options of the 9500B Series. The addition of an active head can improve performance, extend the frequency range, or increase the degree of automation of the 9500B oscilloscope calibration solution.
9510，1.1 GHz Active Head, 500 ps Pulse Rise Time - The 9510 is compatible with all 9500B mainframes, providing 1A sparked sine wave of 1 GHz (or the higher frequency of the host, whichever is lower). When used with any host, pulses with a rise time of 500 ps can be output.
9530，3.2 GHz active head, 150 ps and 500 ps pulse rise times- The 9530 is compatible with all 9500b mainframes, providing 3A steady sine wave of 2 GHz (or the higher frequency of the host, whichever is lower).

Unmatched by any other oscilloscope calibrator. When used with the 9500B 3200 mainframe, the 9560 produces a 6 GHz signal. If you would like to upgrade your existing 9500 console to this level of performance, please contact Fluke.
The active head is a small, precision-engineered module (only 14 x 6.).5 x 3 cm) and connected to the 9500B main unit via two cables (signal and control). Inside the signal head is the circuit that generates the signal needed to calibrate the oscilloscope. Includes precision DC levels up to 220 V;Calibrated square wave up to 210 V peak-to-peak at frequencies from 10 Hz to 100 kHzFrom 0Sine wave with a steady amplitude from 1 Hz to 6 GHz (depending on the signal head);and 0Four different forms of time-scale signals from 2 ns to 50 s. The mixing circuit inside the head can even output externally generated high-frequency calibration signals from the active head. The hybrid circuit also includes a sine wave amplitude sensing circuit, a bandwidth attenuation network, a pulse generator, a fast-edge generator, and an output signal multiplexing switch. The key to providing absolute performance is the distance between the output circuit of the signal head and the input of the oscilloscope amplifier. In a traditional cable connection environment, mismatched, unknown, or unavoidable cable transmission characteristics, and inappropriate connections are all causes of signal attenuation between the calibrator output and the oscilloscope input. With an active head, there is actually only a few millimeters between the calibrator output and the oscilloscope input. This close range includes matched impedances, microstrip transmission lines, and high-quality BNC or SMA connectors, eliminating calibration signal attenuation, distortion, and uncertainty**. The 50 terminators, which can be automatically switched internally, eliminate the need for an external terminator when connecting to a high impedance oscilloscope input.
The introduction of the 9560, a new addition to the active head family, reaffirms our commitment to oscilloscope calibration. As we continue to focus on protecting your investment, the 9560 Active Head is a new addition to deliver on this promise, allowing 9500 users to upgrade their equipment to the current state of the 9500b and enjoy the performance enhancements that come with the new product. The 9560 is capable of delivering a sine wave with a steady amplitude of 6 GHz and a pulse edge of only 70 ps. Unlike other oscilloscope calibrators, you're not limited to pulses of fixed amplitude. Active head technology allows you to adjust the output amplitude to 444 mv and 31 V so that you can detect the oscilloscope within its optimal sensitivity range. Regardless of the amplitude you choose, controlled waveform filtering ensures that all high-speed edges have an precisely defined harmonic energy distribution.
The amplitude of the fast edge ranges from 444 mv to 31 V, 70 ps, 150 ps, or 500 ps rise and fall times, is used to check the oscilloscope vertical deflection The impulse response and bandwidth of the acquisition amplifier. The fast edge of the high voltage level is up to 210 V p-p-p, which checks the dynamic performance of the input attenuator. The frequency of the sine wave is 600 MHz, 11 ghz、3.2 GHz or 6 GHz with 4 amplitudes at 50 GHz44 mv to 556 V p/p (Amplitude of 8. for a load of 50 when using the 9560 active head.)88 mv - 5.56 V p/p), the bandwidth of the oscilloscope can be calibrated directly. It can also calibrate the z-axis and horizontal deflection bandwidth. The dual sinusoidal outputs calibrate the trigger sensitivity and other functions of the oscilloscope, eliminating the need for a power divider.
The DC level and square wave from 10 Hz to 100 kHz are adjustable with amplitude up to 220 V, with a 5-digit amplitude resolution and an accuracy of 0 DC level025%, the accuracy of the square wave is 005% is more than enough for calibrating 12-bit and 14-bit digital indifference oscilloscopes. The 9500B can even check the input impedance of the oscilloscope before adding high voltage to protect the 50 inputs. The automatic conversion to 50 output impedance provides the same waveform with an amplitude of 556 V (Except for 9560, where the supply impedance is compensated by recalibrating the small value, which is (8.)88 mv - 5.56 v）。
The hour marker signal is covered from 0. per squareTime-base calibration in the range of 2 ns to 50 s per s. There are four types to choose from, and every 10th mark can be highlighted to increase its amplitude for proper visibility on both analog and digital storage oscilloscopes.
Square wave and pulse markers can also be used to calibrate time base jitter. The 9500B calibrator has a highly stable reference crystal oscillator with 025 ppm timing accuracy enables calibration of new digital storage oscilloscopes.
