34941A and 34942A SCPI Programming Examples
The programming examples below provide you with SCPI command examples to
use for actions specific to the RF MUX switch modules.
The slot and channel addressing scheme used in these examples follow the form
sccc where s is the mainframe slot number (1 through 8) and ccc is the channel
number. For information on specific configurations, refer to the simplified
schematic on
For complete information on the SCPI commands used to program the 34980A,
refer to the Keysight 34980A Programmer's Reference which can be downloaded
from www.keysight.com/find/34980A.
Example: Closing channels
modules. When you close a channel, any already-closed channels open
automatically. The relays switch in sequence to avoid momentary connection of
the wrong input to the multiplexer output. The following command closes channel
03 on Bank 1 of an RF MUX module in slot 5.
ROUTe:CLOSe (@5103)
Example: Querying channels for open or close state
commands returns the close or open state of channel 33 of a module in slot 5.
ROUT:CLOSe? (@5033)
ROUT:OPEN? (@5033)
Example: Querying the system for module identify
returns the identify of the module installed in slot 7.
SYSTem:CTYPe? 7
Example: Reading the cycle count for a relay

banks. The cycle count is the greater of the three values on the specified bank
(i.e., reflecting the cycle count for the entire bank). Therefore, the count for
Channels 101, 102, 103, and 104 will always be equal. The following statement
reads back the number of completed cycles for the channels 101 and 202 on a
module installed in slot 6.
