Digital Output Operations
The multifunction module (34907A) has two non-isolated 8-bit input/output ports
which you can use for outputting digital patterns.
– The digital output channels are numbered “s01” (lower byte) and “s02” (upper
byte), where s represents the slot number.
– You cannot configure a port for output operations if that port is already
configured to be part of the scan list (digital input).
– From the front panel, you can write to one 8-bit output port at a time. From the
remote interface, you can write to both ports simultaneously.
– From the front-panel only, you can specify whether you want to use binary or
decimal format. Once you have selected the number base, it is used for all
input or output operations on the same port.
–A Factory Reset (*RST command), Instrument Preset (SYSTem:PRESet
command), and Card Reset (SYSTem:CPON command) from the remote
interface will reconfigure both ports as input ports.
– Front-Panel Operation: After selecting the output port, press to edit the
bit pattern or decimal value (the least significant bit is on the right). Press
again to output the bit pattern. To cancel an output operation in
progress, wait for the display to time out.
From the front-panel only, you can specify whether you want to use binary or
decimal format.
USE DECIMAL , USE BINARY
A
from the front panel resets only the port currently selected (both ports
are not reset).
