Specifications

SCAN:PORT [ROUTe:]SCAN:PORT <port> enables or disables the tree isolation
switches (FET multiplexers), or the AT, BT, and AT2 tree switches (relay
multiplexers).
SCAN:PORT ABUS closes the appropriate tree switches for
the analog bus connections. The
[ROUTe:]SCAN:PORT NONE command
disables the tree switches and leaves them open.

Discrete ABUS | NONE
Comments • Order of Command Execution: The [ROUTe:]SCAN:PORT
command must be executed before the [ROUTe:]SCAN <channel_list>
and
[ROUTe:]CLOSe <channel_list> commands.
• *RST Condition: [ROUTe:]SCAN:PORT NONE
Example Selecting the ABUS Port
TRIG:SOUR EXT Selects external trigger source.
SCAN:MODE VOLT Selects the voltage scanning mode.
SCAN:PORT ABUS Selects the ABUS port.
SCAN (@100:107) Sets channel list.
INIT Starts scanning cycle.
SCAN:PORT? [ROUTe:]SCAN:PORT? returns the current state of the analog bus port.
The command returns
NONE if the analog bus connection control relays are
disabled or
ABUS if the control relays are enabled.
Example Query Scan Port
This example selects the analog bus port, then queries the state. Because
the analog bus port is selected, the query command returns
ABUS.
SCAN:PORT ABUS Selects the ABUS port.
SCAN:PORT? Query the port selection.
