The HP 8756A Scalar Network Analyzer, features two independent display channels with separate controls. Complete measurements can be performed using only five control keys for each channel. Measure insertion loss and gain, return loss, and absolute power quickly and accurately with the HP 8756A scalar network analyzer. These scalar measurements can be performed over a broad 10 MHz to 60 GHz frequency range. The HP 11664 diode detectors and AC modulation make accurate, reliable, and drift-free measurements. High-directivity directional bridges covering RF and microwave frequencies produce excellent reflection measurements. Since all of the controls of the HP 8756A are completely programmable, computer-controlled automatic systems can make full use of the HP 8756A and its built-in features. Specifications. Function: The HP 8756A processes and displays the demodulated 27.8 kHz signals from the HP 11664 detectors and the HP 85020 or 85027 bridges. Dynamic range: + 10 dBm to -50 dBm in all three inputs (A, B, and R) . Dynamic accuracy: dynamic accuracy of a single channel measurement using HP 11664A/D/E Detector. Measurement taken over + 10 to -50 dBm at 25°C and at 50 MHz; ±(0.1 dB + 0.01 dB/dB) from +10 to -40 dBm; ±(0.2 dB + 0.02 dB/dB) from -40 to -50 dBm. Scale resolution: 0.1,0.2,0.5, 1, 2,5, 10, or 20 dB per division. Independently controlled for each measurement channel. Reference oHset: offset level adjustable in 0.01 dB increments from -70.00 to +20.00 dBm (absolute) or-90.00 to +90.00 dB (ratio). Resolution Vertical: 0.006 dB for display; 0.01 dB for "Display Cursor." Horizontal: 401 points. Adjustable horizontal resolution (101, 201 or 401 points) is available as Option H20. Sweep time: minimum sweep time >= 150 ms (50 ms with Opt. H20) . Averaging: 2, 4, 8, 16,32,64, 128, or 256 traces may be averaged. Independent control of each display channel. Normalization: traces are stored and normalized to 0.006 dB resolution, independent of scale/ division or offset. The horizontal resolution is 401 points.
