4195A network/spectrum analyzer

First Catalog 1988
Last Catalog 1997
Frequency range 10Hz - 500 MHz
Power (source) -50 to +15 dBm

From 1988 HP Catalog :

The HP 4195A is a high performance, cost effective and intelligent analyzer with combined vector network and spectrum analysis capabilities. The frequency is covered from 10Hz through 500MHz with an excellent 0.001 Hz resolution for audio, baseband, HF, VHF and IF applications. It directly measures amplitude ratio, phase, group delay and spectrum level […]

The 4194A was replaced by the 4395A around 1998.
