The 3577A Network Analyzer is a high performance analyzer which measures impedance parameters in the 5Hz to 200MHz frequency range. The 3577A is fully programmable with the HP-IB bus. Basic measurements provided include magnitude/phase, insertion loss, electrical length, gain compression, and group delay. With the 35677A/B S-parameter test set, this unit can also measure return loss, reflection coefficients, and impedance in 50 or 75 ohm systems. Provides high-speed/high accuracy measurements. Resolutions of up to 0.001Hz, 0.1 dB, 0.005 degree, 1 ps.RF connectors are type N female.
