HP E1367A - Manual (Page 15)

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,
SCAN (@100:213) is
acceptable, but SCAN (@213:100) generates an error.
Example: RF Multiplexer Channel Lists/Ranges
Channel Lists:
CLOS (@100,112) ! Close channels 00 and 12 on card 01
OPEN (@203,210) ! Open channels 03 and 10 on card 02
Channel Ranges:
OPEN (@100:113) ! Open all channels on card 01
SCAN (@100:213) ! Scan all channels on cards 01 and 02
Initial Operation
An example program follows which uses Hewlett-Packard BASIC and SCPI
language to get you started using the RF multiplexers. The computer used in
the example is an HP 9000 Series 200/300 (or equivalent) controller with HP
BASIC as the program language. The computer interfaces to the mainframe
using the Hewlett-Packard Interface Bus (HP-IB)
*
.
This program closes channel 02 of an RF multiplexer at logical address 120
(secondary address = 120/8 = 15) and queries the channel closure state. The
result is returned to the controller and displayed (1 = channel closed, 0 =
channel open). See the HP B-size configuration guide for information on
addressing.
Example: Close Multiplexer Channel
OUTPUT 70915;"CLOS (@102)" ! Close channel 02
OUTPUT 70915;"CLOS? (@102)" ! Query channel 02 state
ENTER 70915;Value ! Enter result into Value
PRINT Value ! Display result
