• High (40 dB) directivity bridges
• "Autoscale" for fast measurements
• Full HP-IB programmability
• Fully annotated digital display
• Nine "Save/Recall" registers
• Direct digital plot capability

Measure insertion loss and gain, return loss, and absolute power quickly and accurately with the 8756A scalar network analyzer. These scalar measurements can be performed over a broad 10MHz to 60GHz frequency range.

The 8756A features two independent display channels with separate controls. Complete measurements can be performed using only five control keys for each channel.

Make even faster measurements with one key - the "Autoscale" key. Press it and the built-in microprocessor chooses the optimum scale and reference level to display your measurement. Use the convenient display cursor to read out magnitude and frequency at each data point.

When used with the 8350B sweep oscillator or 8341B/8340B synthesized sweepers, the 8756A acts as a system controller by managing the other instruments through the "8756 System Interface." Using the system interface, the 8756A extracts frequency information from the sweeper and uses it to annotate the digital display.

When used alone, the 8756A can save and recall up to nine front-panel states. With the 8350B or 8340B/41B, it saves and recalls not only its own front-panel state, but the sweeper's as well.

Another benefit of the 8756A/8350B combination is "Alternate Sweep"; the ability to sweep two different frequency ranges or power levels and display them simultaneously.

System control also extends to an HP-IB digital plotter. The 8756A can directly plot the CRT's image onto a plotter such as the 7475A or 7440A. Crisp, permanent, annotated plots can be created just by selecting the PLOT soft key. Adjustable horizontal resolution (101, 201 or 401 points) is available as Option H20.
