SYSTEM OVERVIEW

Series 373XXA Vector Network Analyzers are ratio measurement sys-

 

 

tems used to measure complex vector signal characteristics (real/imagi-

 

 

nary, magnitude/phase, etc) of devices and systems in the 22.5 MHz to

 

 

65 GHz frequency range.

The 373XXA performs these measurements by sourcing a stimulus sig- nal to the Device Under Test (DUT) that is connected to the front panel Port 1 and/or Port2 connectors. (See Figure 7-1 on page 7-5). It simultaneously measures the DUT response, which consists of re- flected and/or transmitted (attenuated, or amplified) signals at the connectors of the DUT. The reflected and/or transmitted signal(s) and a sample of the stimulus signal, are down converted and then trans- formed into their real and imaginary vector components. The resul- tant vector components are measured and converted into digital infor- mation. This digital information is sent to the Main Processor PCB where the desired S-parameter data is normalized and then presented to the user via the front panel color display. The display information is also sent to the rear panel VGA Out connector for use with an external VGA monitor.

The normalized measurement information is also sent to the rear panel Printer Out connector for use with an external printer and/or plotter.

A front panel keypad, a rotary knob, and an IBM compatible keyboard interface provide user interaction with 373XXA Main Processor PCB.

The system is equipped with internal hard disk and floppy disk drives and battery backed internal memories for storage and retrieval of data and front panel setup information.

The 373XXA implements an IEEE 488.2 interface. This GPIB inter- face allows an externally connected instrument controller to control the 373XXA system in the “Remote-Only” mode. All 373XXA measure- ment and input/output operations may be controlled remotely in this mode.
