The HP 3577A Network Analyzer provides cost-effective, high performance network measurements from 5 Hz to 200 MHz for higher productivity in design and production. The companion HP 35677A/B S-Parameter Test Sets and full line of accessories ensure a complete measurement solution. Innovative analog and digital design are combined for superb accuracy, resolution and operational simplicity. Convenient soft-key selection of measurement functions allows you to quickly measure transfer functions, magnitude/phase, insertion loss/gain, attenuation, electrical length and gain compression. In addition, measurement of phase distortion parameters such as group delay and deviation from linear phase can be made with high resolution. With the HP 3577A's flexible receiver input impedances, you can measure in either 50 Ohm or high impedance (1 Megohm) environments. Use the HP 35677B S-Parameter Test Sets with the HP 3577A to make reflection measurements such as return loss, reflection coefficient and impedance in 50 Ohm or 75 Ohm systems, while simultaneously displaying transmission parameters. * 5 Hz to 200 MHz .High Speed/high accuracy measurements .0.001 dB, 0.005 degree, 1ps, 0.001 Hz resolution .Built-in three-term error correction plus normalization .Magnitude, phase, polar, real, imaginary, and group delay display modes .Convenience features including direct plotter control and vector math functions GPIB.
