ROUTe:OPEN
ROUTe:OPEN
Syntax
ROUTe:OPEN (@<ch_list>)
ROUTe:OPEN? (@<ch_list>)
Description
This command opens the specified channels on a multiplexer or switch module.
Used With:
- All modules except 34907A
Parameters
Name Type Range of Values Default Value <ch_list> Channel List One or more channels, as shown:
(@310) - channel 10 on the module in slot 300.
(@305:310) - channels 05 through 10 on the module in slot 300.
(@202:207,209,302:308) - channels 02 through 07 and 09 on the module in slot 200 and channels 02 through 08 on the module in slot 300.
This is a required parameter.
Remarks
- For the matrix modules, the channel number represents the intersection of the desired row and column. For example, channel 234 represents the intersection of row 3 and column 4 on the module in slot 200 (assumes two-wire mode). For more information, see the simplified schematics.
- The RF Multiplexer modules (34905A, 34906A) will not respond to the ROUTe:OPEN command (an error is generated). To "open" a channel on these modules, send the ROUTe:CLOSe command to a different channel in the same bank.
- As part of the scan setup, the ROUTe:SCAN command examines the scan list and determines which channel relays and Analog Bus relays will be impacted by the scan. The following rules will apply once the scan is initiated and will impact what relays can be manually opened and closed.
- When the scan is initiated, the instrument will open all channels in modules that contain one or more channels in the scan list.
- While the scan is running, the instrument prohibits use of all channels in modules that contain one or more channels in the specified <ch_list> (these channels are dedicated to the scan).
Return Format
The query returns 1 if the specified channel is open or 0 if the specified channel is closed. Multiple responses are separated by commas.
Examples
The following command opens channels 03 and 13 in slot 100.
ROUT:OPEN (@103,113)
The following command opens channel 03 on the matrix module in slot 300.
ROUT:OPEN (@303)
The following command opens channels 01 through 08 on the matrix module in slot 300.
ROUT:OPEN (@301:308)
The following query reads the state of channels 03 and 06 in slot 100 (1 = open; 0 = closed).
