Advantest R3754A

This network analyzer 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 Network 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.

The R3754A is the 150MHz vector network analyzer, which has newly been designed based on a concept “an optimum tool for each application”.

The manufacturer have fully pursued high throughput such as 50 micros/points high-speed measurement at a resolution bandwidth (RBW) of 15KHz, 127 dB (RBW 1KHz) wide dynamic range measurement and two device simultaneous measurement with two-channel/four-trace display.

The program sweeping function that can freely change the resolution bandwidth (RBW), output level, and input attenuator during sweep operation for each segment has been added.

Since the R3754A employs semiconductor switches for changing the output level and for switching the input attenuator, it allows the optimum high-speed level sweeping for the drive level test of the oscillator.

The R3754A has wide dynamic range of 127 dB with switching of input attenuator/preamplifier. R3754 offers high speed and long life using semiconductor switches for switches input attenuator (RBW 1 kHz).

For each segment, the R3754A allows setting of frequency, output level, input attenuator, RBW and setting time.

By using an MS-DOS personal computer, it is possible to easily create programs and analyze data because of the disk conformed to MS-DOS format standard. Three modes of storage capacity are available (DD 720 KB, HD 1.2 MB and HD 1.44 MB).

The R3754A has a built-in controller with which a high-speed ATE system can be easily configured with no external controller for processes from adjustment to inspection.
