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_list> 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
