Agilent Technologies 34401A Front / Rear Input Terminal Switching, Remote Interface Operation

Chapter 3 Features and Functions

Measurement Configuration

Integration Time	• Front-Panel Operation: Integration time is set indirectly when you
(continued)	select the number of digits. See the table for resolution on page 54.
	• Remote Interface Operation:
	<function>:NPLCycles {0.020.2110100MINimumMAXimum}
	For frequency and period measurements, aperture time (or gate time)
	is analogous to integration time. Specify 10 ms (41⁄2 digits), 100 ms
	(default; 51⁄2 digits), or 1 second (61⁄2 digits).
	FREQuency:APERture {0.010.11MINimumMAXimum}
	PERiod:APERture {0.010.11MINimumMAXimum}

Front / Rear Input Terminal Switching

Any measurement made using the front terminals can also be made using the input terminals on the rear panel. See “The Front Panel at a Glance,” on page 2, for the location of the front /rear switch.

The input terminals can only be configured from the front panel. You cannot select the terminals from the remote interface, but you can query the present setting.

• The Rear annunciator turns on when you select the rear terminals.

• Remote Interface Operation: You can query the multimeter to determine whether the front or rear input terminals are selected.

ROUTe:TERMinals? returns “FRON” or “REAR”
