For Measuring Transmission/Reflection and S-Parameter

NETWORK ANALYZER

MS4661A/E, MS4662A

100 kHz to 3 GHz

PTA GPIB

The MS4661A/E include a built-in transmission/reflection measure­ment test set (bridge), making them ideal for measuring antennas and
passive devices (filters, attenuators, switches, cables) where the input
and output impedances are nearly equal. The MS4662A also has an
S-parameter test set. In addition to measuring active devices with dif­ferent input and output characteristics (such as amplifiers), it mea­sures forward and reverse direction characteristics with a single con­nection. You can choose the model best suited to your application.
The MS4661A and MS4662A has color LCD displays, while the
MS4661E has an EL display (monochrome).

The high-speed synthesizer and DSP (digital signal processor) per­mit measurements at 400 µs/point (or 600 µs/point using two-port cal­ibration), with sweep times approximating real-time measurement.
Post-measurement data analysis is facilitated by unique functions
such as limit tests, 3 dB bandwidth searches, and ripple searches for
device evaluation and pass/fail identification. With PTA (Personal Test
Automation) capability as standard, it is easy to configure ATE
(Automated Test Equipment) systems.

Features

•

Built-in transmission/reflection measurement, and S-parameter test set

• Full range of limit test functions for real-time pass/fail testing

• One- touch measurement of each characteristic using target data

search function

• Time domain analysis

Application examples

•

Measurement of cable fault locations

Time-domain function permits measurement of distances to cable faults
and impedance mismatch points.

• Simultaneous measurement of amplifier forward/reverse direction

transmission (MS4662A)

The S-parameter test set in the MS4662A allows you simultaneous
measurement of forward and reverse direction device characteristics.

Model

• Filter pass/fail judgment using limit tests

The segment limit test permits pass/fail testing for complex charac­teristics with subtle fluctuations in slope not detected as ripples.

• Filter analysis using target data search

This function is useful in filter 3 dB bandwidth measurements and
ripple searches.
