SCAN:MODE
[ROUTe:]SCAN:MODE NONE | VOLT | RES | FRES sets the scan mode for
the RF multiplexers. NONE , VOLT , and RES have no effect on multiplexer
operation. With FRES , the switch is set for “paired-channel” scanning.
That is, when a channel in bank 0 is closed, the associated channel in bank 1
is simultaneously closed.

Comments
•
Order of Command Execution: The [ROUTe:]SCAN:MODE
command must be executed before the [ROUTe:]SCAN < channel_lis t>
command.
•
FRES Mode Description: With FRES , and channel closed in bank 0
automatically closes the paired channel in bank 1. For example, with
FRES , closing channel 00 also simultaneously closes channel 10,
closing channel 01 closes channel 11, etc. Use only channels 00-03
for the channel_list. Specifying channels 10-13 causes an error.

*RST Condition: ROUT:SCAN:MODE NONE
Example Selecting Paired-Channel Scanning
TRIG:SOUR EXT ! External trigger source
SCAN:MODE FRES ! Paired-channel scanning mode
SCAN (@100:103) ! Select channels for scanning
INIT ! Start scanning, close channels
100 and 110
SCAN:MODE?
[ROUTe:]SCAN:MODE? returns the current state of the scan mode. The
command returns " NONE " , "VOLT ", "RES " , or " FRES " depending on
the [ROUTE:]SCAN:MODE parameter setting.
Example Query Scan Mode
Since this example selects the FRES (paired-channel scanning), the query
command returns " FRES ".
SCAN:MODE FRES ! Selects paired-channel scanning
SCAN:MODE? ! Query scanning mode
