Data Acquisition Overview Measurement Software Data Acquisition Circuitry...
Page 13: Data Acquisition Overview
Introduction to the 34980A Data Acquisition Overview You can use the Agilent 34980A as a stand- alone instrument, but for most applications you will want to take advantage of its PC connectivity and remote operation capabilities. A simplified data acquisition system is shown below.
Page 14: Measurement Software
Agilent 34832A BenchLink Data Logger Pro is a Windows®- based application available on CD from Agilent. It is designed to make it easy to use the 34980A with your PC (over GPIB, USB or LAN) for collecting and analyzing data.

Page 16: Data Acquisition Circuitry
Introduction to the 34980A Data Acquisition Circuitry As shown below, the 34980A's main system processor controls all of the basic functionality of the instrument. This is where the instrument communicates with the plug- in modules, interacts with command transactions over the remote interfaces, and controls the optional internal DMM.
Page 17: Plug-In Modules
Introduction to the 34980A Plug-In Modules The 34980A offers a complete selection of plug- in modules to give you high- quality measurement, switching, and control capabilities. The plug- in modules communicate with the main system processor via the internal digital bus. The multiplexer modules also connect to the internal DMM via the internal Analog Buses.
Page 18: Transducers And Sensors
TTL levels Alarm Limits The 34980A has four alarms which you can configure to alert you when a reading exceeds specified limits on a channel during a scan. You can assign a high limit, a low limit, or both to any configured channel in the scan list.
Page 19: Signal Routing And Switching
Signal Routing and Switching The switching capabilities of the plug- in modules available with the 34980A provide test system flexibility and expandability. You can use the switching plug- in modules to route signals to and from your test system or multiplex signals to the internal DMM or external instruments.
Page 20: Matrix Switching
You can use General Purpose (GP) switches to control power connections to your DUTs, control status indicators, or actuate external power relays or solenoids. The GP switches for the 34980A are available in two switch configurations as shown below. Form C...
Page 21: Rf And Microwave Switching
RF and Microwave Switching A variety of RF and microwave switch modules are also available for the 34980A. This includes RF multiplexers (34941A, 34942A), SPDT switching from dc to 20 GHz (34946A, 34947A), and a switch/attenuator driver module (34945A) that allows you to control switches or attenuators external to the 34980A mainframe.
Page 22: Measurement Input
Introduction to the 34980A Measurement Input The 34980A allows you to combine a DMM (either internal or external) with multiplexer channels to create a scan. During a scan, the instrument connects the internal DMM to the configured multiplexer channels one at a time and makes a measurement on each channel.
Page 23: Analog-To-Digital Conversion (Adc)
The ADC takes a prescaled dc voltage from the signal- conditioning circuitry and converts it to digital data for output and display on the 34980A front panel. The ADC governs some of the most basic measurement characteristics. These include measurement resolution, reading speed, and the ability to reject spurious noise.

Page 25: Scanning With External Instruments
Scanning With External Instruments If your application doesn't require the built- in measurement capabilities of the 34980A, you can order the mainframe without the internal DMM. In this configuration, you can use the 34980A for signal routing or control applications. If you install a multiplexer plug- in module, you can use the system for scanning with an external instrument.
Page 26 (including channel delay). The 34980A outputs a Channel Closed pulse. In response, the external instrument must notify the 34980A when it has finished its measurement and is ready to advance to the next channel in the scan list. For more information, see “Scanning...
