Scanning and triggering

scan.addwrite()

This function writes a specified value to a channel at the added step in the scan.
Type TSP-Link accessible
Function Yes
Usage
scan.addwrite("channelList", writeValue)
scan.addwrite("channelList", writeValue, width)
channelList
writeValue
width
Details
This command is similar to issuing channel.write() at the scan step. Specifying multiple channels
in channelList causes multiple steps to be added to the scan.
For digital I/O channels, only a width of 1, 2, 3, or 4 is supported. Any information (bits) greater than
the specified width are ignored. Values written to inputs are ignored. If no specified channel is set for
output, an error is generated. If a width crosses channels, only the channels set to output are
affected.
This is not available for backplane and switch channels.
For DAC channels, if the channel mode is changed after the scan is created, the scan is rebuilt. If the
write value is no longer compatible with the new mode, an error is generated and the scan becomes
invalid.

Series 3700A System Switch/Multimeter Reference Manual
Set channel 1001 to 4-pole operation.
Adds a single step that closes channels
1001, 1031, and 1911, and then takes a DC
voltage measurement.
Adds three steps with the following actions:
▪
Closes channels 1101, 2202, and
1911, and then takes a DC voltage
measurement.
▪
Opens channel 1101, closes 1102 and
maintains 1911 and 2202 closed, and
then makes a DC voltage
measurement.
▪
Opens channel 1102, closes 1103 and
maintains 1911 and 2202 closed, and
then makes a DC voltage
measurement.
