Setting The Handshake Line Parameters - Agilent Technologies 34950A User Manual

Handshaking
You can set parameters by using a sequence of commands instead of the
CONFigure
sets the handshaking mode to synchronous, the output drive to open
collector, and the handshake rate to 1 MHz.

Setting the Handshake Line Parameters

You can set the handshake lines' input threshold, output drive mode, and
output drive voltage. These settings affect all the handshake lines in the
bank. Handshake line polarity can be set for each individual handshake
line.
For example, you can invert the polarity of the handshake line H1 on
bank 2 with the following command.
CONF:DIG:HAND:POL INV, H1, (@1201)
You can set the output drive mode, output voltage, and input threshold for
all handshake lines in each bank. For example, the following commands set
the drive mode to active, the drive voltage to 4.5 V, and the input
threshold to 1.0 V on bank 2.

macro command. For example, the following command sequence
The settings for drive mode, output drive level, and input threshold also
apply to the bank's interrupt line.
When using external pull-ups in the open collector mode, the outputs will
not exceed 5 V.
