34410A/11A/L4411A User’s Guide 49
Features and Functions 2
• Remote Interface Operation: Refer to the MEMory command subsystem in the
Agilent 34410A/11A/L4411A Programmer’s Reference Help for a complete
description and syntax of the commands that store, recall, and name
multimeter states from the remote interface.
Accessing Reading Memory
Reading memory is accessed directly from the remote interface only.
The multimeter’s reading memory is a first–in–first–out (FIFO) buffer holding
up to 50,000 readings (34410A) or 1 million readings (34411A/L4411A). The
oldest readings are preserved.
• Remote Interface Operation: The following command transfers readings stored
in non–volatile memory into the multimeter’s output buffer, from where
you can read them into your computer:
FETCh?
The following command will obtain whatever readings are present in
NVMEM, and erase them as they are read:
R?
Refer to the Agilent 34410A/11A/L4411A Programmer’s Reference Help for
a complete description and syntax for these commands.
Front/Rear Input Terminal Switching (34410A/11A)
• Front Panel Operation: The Front/Rear switch manually selects the set of input
terminals (front or rear) that is connected internally for measurements.
Both sets are equivalent and include Sense (LO and HI), Input (LO and HI), and
Current (
I
) terminals. The Rear annunciator is lit when the rear inputs are
selected. See “The Front Panel at a Glance (34410A/11A)” on page 8, for the
location of the Front/Rear switch. The Front/Rear switch has no effect on the
Ext Trig or VM Comp connectors.
Do not change the position of the Front/Rear switch while signals are present on either
the front or rear set of terminals. Switching while high voltages or currents are present
may cause instrument damage, and may increase the risk of electric shock.
