Used Keysight / Agilent 3577A Network Analyzer, 5Hz to 200MHz, Three-input, Dual-trace

Product Highlights

The HP 3577A measures network performance in the frequency range of 5 Hz to 200 MHz. Each of the three test input ports, R, A, and B, provide 100 dB of dynamic range. A front panel "line stretcher" is available with a readout in meters and centimeters. The line stretcher enables the electrical length of the R channel to be changed to match the electrical length of the test port used. This allows compensation for differences in test cable lengths and to measure the electrical length of networks under test. Each of the three test inputs can be displayed on one or both traces. The traces are labeled Trace 1 and Trace 2. Trace data for each trace is digitally stored as complex data in a trace memory. This results in the ability to display the same data in any of seven display formats. The 3577A display has no etched lines. The graticule is drawn as part of the display operation. No screen overlays are required for polar or Smith charts. The 3577A can perform complex trace arithmetic with the trace storage capability, as well as one-port correction routines. Other features include adjustable receiver bandwidth, complex trace averaging, and automatic plot routines. The 3577A source output frequencies can be swept from 5 Hz to 200 MHz. The same synthesizer drives both the source and input channel tuners, so that the source and receiver are always tuned to the same frequency. The source and receiver frequencies are coupled; therefore, only linear devices can be characterized. The source output level can be set between +15 dBm and -49 dBm. The source amplitude can also be swept. The 3577A features menu-driven operation, using eight "softkeys". The menus are accessed by pressing the labeled hardkeys, and the appropriate softkeys select the desired parameters for the hardkey function. Marker and sweep parameters are presented on the 3577A display.
