Wiltron 560A Scalar Network Analyser

The 560A Network Analyser provides swept frequency displays of transmission loss/gain, return loss, and power. A Network Analyser Test Set consists of a receiver/display unit, an SWR Autotester (sold separately), and Detectors (also sold separately). Frequency range: 1 MHz to 34 GHz, depending on the SWR Autotester and Detectors used (sold separately) Channels: Three (A, B, R) with push-button selection of A, B, R, A-R, and B-R. Two channels are displayed simultaneously Dynamic measurement range and sensitivity: A and B with Detectors (sold separately): 66 dB (+16 dBm to -50 dBm); A and B with SWR Autotester (sold separately): 66 dB (+16 dBm to 50 dBm); R with Detector (sold separately): 46 dB (+16 dBm to -30 dBm) Offset control: positioning of A and B traces is independently and continuously adjustable over >?65 dB range. When trace is on reference line, power is displayed in dBm on 3 digit LED readout with 0.1 resolution. Offset is displayed in dB relative to a 0 dB reference level Resolution: independent control for A and B in steps of 0.2, 0.5, 2.5, 10 dB per division Store trace: stores displayed trace(s) in 1024 point memory Average: averages data in memory with input test data and displays the result Subtraction: subtracts data in memory from input test data and displays the result Recall: Displays stored data Uncalibrated sweep indicator: lights when external sweep generator sweep rate is too fast for memory Real time display mode: horizontal sweep is synchronized with ramp from external sweep generator Refresh: steady, non flickering display is provided regardless of sweep generator sweep rate. Vertical resolution is 512 points for single or dual traces Refresh hold: Updating of display data is stopped, display is frozen X-Y plot (real time): provides pen lift, vertical, and horizontal signals for X-Y plot, coincident with external sweep generator ramp X-Y plot (refresh): display is frozen and then plotted at 30 second sweep rate CRT: 8 vertical by 10 horizontal divisions. One division is = 1.22 cm. Single beam, standard persistence (P31) phosphor CRT with internal graticule
