Configuring the Agilent E8462A Multiplexer 31
Channel Numbers,
Ranges, and Lists
The Agilent E8462A Multiplexer channel numbers are 0000 through 0255
under the 1-wire mode. The channels can be addressed using individual
channel numbers or channel ranges.
Note For all other modes, the “channel” is actually used to refer to the paired
channel. Under 2-wire mode, there are 128 2-wire paired channels, under
3-wire and 4-wire modes, there are only 64 paired 3-wire or 4-wire
channels. See Chapters 2 and 3 for more information of paired channels.
Use commas (,) to form a channel list or use a colon (:) to form a channel
range. Only valid channels can be accessed in a channel list or channel
range. Also, the channel list or channel range must be from a lower channel
number to a higher channel number. For example,
CLOS(@1000:1015) is
acceptable, but
CLOS(@1015:1000) generates an error.
Using the channel range
(@cc0000:cc9999) with the SCAN command
causes all channels to be scanned except the tree relays (CH9000-9204).
Tree relays switch the channels to the appropriate terminal lines and
therefore are not included in a scan list.
Below are some SCPI commands and a description of their effect on channel
lists and ranges.
Channel Lists:
FUNC 1, WIRE2
Set the module to 2-wire mode.
CLOS(@1000,1001)
Close paired channels 000 and
001 on card #1 (channels 0, 1,
32 & 33 will be closed together).
OPEN(@1003,1010)
Open paired channels 03 and 10
on card #1.
Channel Ranges:
FUNC 1, WIRE1
Set the module to 1-wire mode.
OPEN (@1000:1255)
Open all channels on card #1.
CLOS (@1000,1127)
Close channels 000 and 127 on
card #1.
SCAN (@1128:1255)
Define channels 128-255 to be
scanned.
