Advantest TR4172 Specifications
The TR4172 Spectrum analyzer is a microprocessor-controlled, intelligent instrument with a frequency range from 50 Hz to 1800 MHz. in addition to the spectrum analyzing function, the integrated tracking Generator of TR4172 enables analysis of frequency response of Filter Amplifier and so on TR4172 is the first Spectrum analyzer with a capability for measuring phase response and group delay of Filter or Amplifier at resolutions of down to 0.1 deg and 0.1 ns respectively, up to a frequency of 1800 MHZ.
The integrated tracking Generator along with the analyzer’ร intelligent control capability, permits correction of the analyzer's frequency response itself allowing precision level measurement.

Status
The device is overhauled by Crashjuh, with some help from Maxell and PBX
At present, there are again a number of buttons that refuse service.
These buttons would therefore be replaced by new momentary-contact push buttons.
