E1412A Multimeter Application Examples Keysight E1412A Multimeter Application Information
MEASure Command
The simplest measurement method is using the MEASure command which
configures the function to be measured, initiates the measurement(s) and places
the reading(s) directly into the output buffer. You then must provide the I/O
construct to retrieve the readings and enter them into the computer. One
MEASure command will initiate multiple measurements if the trigger count or the
sample count is greater than 1. The measurement process stops when the output
buffer fills if readings are not retrieved fast enough. The measurement process
restarts when there is again room to store readings in the output buffer.
READ? Command
The READ? command requires that you configure the multimeter for the function
you want to measure prior to issuing the command. The command initiates the
measurement(s) and places the reading(s) directly into the output buffer like the
MEASure command. You then must provide the I/O construct to retrieve the
readings and enter them into the computer. One READ? command will initiate
multiple measurements if the trigger count or the sample count is greater than 1.
The measurement process stops when the output buffer fills if readings are not
retrieved fast enough. The measurement process restarts when there is room to
store readings in the output buffer.
INIT and FETC? Commands
The READ? command is broken down into two operations with the INIT and
FETC? commands. The INIT and FETC? commands require that you configure
the multimeter for the function you want to measure prior to issuing the
commands. The
INIT command initiates the measurement(s) and places the
reading(s) into the multimeter's RAM memory. This memory will hold a maximum
of 512 readings. You use the
FETC? command to transfer the readings from
memory to the output buffer. You then must provide the I/O construct to retrieve
the readings and enter them into the computer. One
INIT command will initiate
multiple measurements if the trigger count or the sample count is greater than 1.
If more than 512 measurements are made, only the last 512 readings are stored.
Use the
READ? command for more than 512 readings since readings are
immediately put into the output buffer and retrieved with an I/O construct you
supply. The measurement process stops when the output buffer fills if readings
are not retrieved fast enough. The measurement process restarts when there is
again room to store readings in the output buffer.
Measurement Format
Readings in the output buffer have the following characteristics:
