6.5.3.4
ROUTe:SCAN:ALTernate <Boolean>
This command sets the scan alternate mode. It is equivalent to selecting be-
tween the PRIM CHAN and SCAN/PRIM options with the SCAN MODE
function in the INPUT soft-key menu. A <Boolean> parameter value of 1 or
ON enables scanning and selects the alternate scan mode where the primary
channel is measured between each channel in the scan list. If the scan state (see
Section 6.5.3.8 ) was previously off it will be set on. A value of 0 or OFF sets
the scan state and scan alternate state off so that only the primary channel is
measured. The *RST command sets this to OFF.
Example command:ROUT:SCAN:ALT ON
6.5.3.5
ROUTe:SCAN:ALTernate?
This query command returns 1 if the alternate scan mode is ON and 0
otherwise.
Example command: ROUT:SCAN:ALT?
Example response: 0
6.5.3.6
ROUTe:SCAN[:LIST] <channel_list>
This command selects input channels for scanning. It is equivalent to selecting
scan channels using the SCAN CHAN soft-key function in the INPUT menu.
This command also sets the scanning state to ON (see Section 6.5.3.8 ) and the
scanning alternate state to OFF (see Section 6.5.3.4 ). It does not affect the
measure mode or INITiate state. The *RST command sets the scan channel list
to all channels selected.
The <channel_list> parameter specifies a list of channels to scan. The channel
list is preceded by @ and enclosed in parentheses. Channel numbers are sepa-
rated by commas. A range can be specified using a colon between two channel
numbers. For example, if you want to select channels 1, 3, 7, and 10 through 15
the list may appear as the (@1,3,7,10:15). If any channel number is greater than
the actual number of channels it will be ignored. Channel numbers may appear
in the list in any order. However, they will always be scanned from the lowest
number to the highest.
Example command: ROUT:SCAN (@2,4)
6.5.3.7
ROUTe:SCAN[:LIST]?
This query command returns the list of channels selected for scanning. The
channel list is preceded by @ and enclosed in parentheses. Channel numbers
are separated by commas. This command returns a list of channels selected for
scanning regardless of whether or not scanning is enabled.
Example command: ROUT:SCAN?
Example response: (@2,3,4)
