rates up to 13 kHz. 
Measurements for this DMM include Vdc/ac, 2- and 4-wire ohms, 
offset-compensated ohms, and temperature from thermocouples, 
thermistors, and RTDs. 
Agilent 34401 Digital
Multimeter
The Agilent 34401 Digital Multimeter (DMM) measures dc voltage, ac-rms 
voltage, and ohms (including 4-wire ohms). It can also measure temperature 
by using thermistors. The input to the DMM is balanced and differential.
Note For additional information, refer to the Agilent 34401 Digital Multimeter 
User’s Guide.
Agilent 53131 Universal
Counter
The Agilent 53131 Universal Counter performs frequency, time interval, 
period, and totalize measurements. It is connected to the UUT through the 
Agilent E8792A 32-Pin Matrix and Instrument Multiplexer Module, but 
uses only one row of the matrix module connector, since the counter inputs 
are referenced to system ground.
Instead of using the 53131 Counter, you can use an Agilent E6182A 
(Agilent E1333A) Universal Counter. This counter is a single slot B-size 
VXI counter that requires an Agilent E1403B B-size to C-size Active 
Adapter Module and cables and a C-size VXI mainframe.
Note For additional information, refer to the Agilent 53131 Universal Counter 
Programming Guide.
Agilent 33120 Arbitrary
Waveform Generator
The Agilent 33120 Arbitrary Waveform Generator (Arb) provides the 
means to generate arbitrary waveform, besides providing standard functions 
like sine, square, etc. It is connected to the UUT through the Agilent E8792A 
32-Pin Matrix and Instrument Multiplexer Module, but since its output is 
floating, it requires two connections to the matrix module.
Instead of using the Agilent 33120 Arb, you can use the Agilent E6173A 
Arbitrary Waveform Generator (formerly Agilent Z2471A). This is a 
register-based, two-channel isolated (both between channels and from 
ground) waveform generator. Channel one is connected to the Agilent 8792 
32-Pin Matrix and Instrument Multiplexer Module. Channel two may be 
connected by the customer directly to a UUT pin or the pin matrix module 
using an unassigned connector pin. Since this is a C-size single slot VXI 
module, it requires a C-size VXI Mainframe.
Note For additional information, refer to the Agilent 33120 Arbitrary Waveform 
Generator User’s Guide.
