Advantest R3965A

The R3965A is a three-port test sets which can be connected to the R3765AH and R3767AH network analyzers and used to measure transmission characteristics and reflection characteristics for three-port devices.

S parameters can be measured in three directions without changing the device connections using the R3965A test set.

The R3965A and the network analyzer must be connected using the rear control cable before turning on the network analyzer ON. If the instrument is connected to the network analyzer after its power has been turned on, the network analyzer cannot control the instrument.

The Advantest R3965A test set is an instrument which measures the complex transmission and reflection characteristics of two port devices in the frequency domain.

It does this by sampling the incident signal, separating the transmitted and reflected waves, and then performing ratios that are directly related to the reflection and transmission coefficients of the two port.

Frequency is swept to rapidly obtain amplitude and phase information over a band of frequencies of interest.

These Analyzers utilize synthesized frequency sources to provide a known test stimulus that can sweep across a range of frequencies or power levels.

It also can perform ratioed measurements (including phase), which require multiple receivers.

This unit can provide a wealth of knowledge about a device under test (DUT), including its magnitude, phase, and group-delay response.
