are qualified to do so.
DO NOT operate damaged equipment: Whenever it is possible that the safety protection features built into this product have been
impaired, either through physical damage, excessive moisture, or any other reason, REMOVE POWER and do not use the product until
safe operation can be verified by service-trained personnel. If necessary, return the product to an Agilent Technologies Sales and Service
Office for service and repair to ensure that safety features are maintained.
DO NOT service or adjust alone: Do not attempt internal service or adjustment unless another person, capable of rendering first aid and
resuscitation, is present.

Chapter 1
Getting Started with the
Agilent E1366A/E1367A RF Multiplexers
Using This Chapter
This chapter includes an RF multiplexer’s description, addressing
guidelines, and an example to check initial operation. Chapter contents are:
• Multiplexer Module Description. . . . . . . . . . . . . . . . . . . . . . Page 11
• Programming the Multiplexer Module . . . . . . . . . . . . . . . . . Page 13

Multiplexer Module Description
The Agilent E1366A 50Ω RF Multiplexer (2 x 4:1) and the Agilent E1367A
75Ω RF Multiplexer (2 x 4:1) are VXIbus and VMEbus B-size
register-based products which provide bidirectional switching and scanning
for user inputs and outputs. The multiplexers can operate in a B-size
VXIbus or VMEbus mainframe or (with an adapter) in a C-size VXIbus
mainframe.
For the RF multiplexers, switching consists of connecting a channel to its
common terminal. Scanning consists of connecting a series of channels
(one at a time) to the appropriate common terminal.
Basic Operation The multiplexers consist of two banks of channels (bank 0 and bank 1) to
form two 4:1 multiplexers. Bank 0 includes channels 00 through 03 and
com 00. Bank 1 includes channels 10 through 13 and com 10. See Figure
1-1 for a simplified switching diagram.
Each channel is switched (connected to its common) by closing the
appropriate (nonlatching) relays. Channels 00 through 03 can be switched
to com 00, and channels 10 through 13 can be switched to com 10. Only
one channel in each bank can be connected to its common at a time.
User inputs and outputs to each channel are made through BNC connectors.
When open (disconnected from common), each channel is terminated in its
characteristic impedance (50Ω for the E1366A, 75Ω for the E1367A).
A termination resistor (50Ω for the Agilent E1366A or 75Ω for the Agilent
E1367A) is mounted on each channel, but can be removed as desired. At
power-on or reset, all channels are open and terminated in their
characteristic impedance, and both commons are open.

Typical
Configuration The multiplexer relays are configured in a “ tree” structure which provides
high isolation and low VSWR (voltage standing wave ratio). Each channel
can switch user inputs up to 42 Vdc or 42 Vac peak. User input frequencies
to the multiplexers can be from dc to 1.3 GHz.
The multiplexers can be configured for several arrangements, such as
standard, tree, or matrix. You can use single scanning, multiple scanning, or
continuous scanning for any configuration.
For a SCPI (Standard Commands for Programmable Instruments)
environment, one or more multiplexers can be defined as a switchbox
instrument. For a switchbox instrument, all multiplexer channels within the
instrument can be addressed using a single interface address.
Programming the Multiplexer Module
To program the RF multiplexers using SCPI, you must select the controller
language, interface address, and SCPI commands to be used. Guidelines to
select SCPI commands for the RF multiplexers follow. See the appropriate
Agilent B-size or C-size configuration guide for interface addressing and
controller language information.
Note This discussion applies to SCPI programming. See Appendix B,
RF Multiplexers Registers, for information on multiplexer registers.
Specifying SCPI
Commands To address specific channels within an RF multiplexer, you must specify the
SCPI command and multiplexer channel address. For the RF multiplexers,
use CLOSe <channel_list> to switch (close) channels and use
OPEN<channel_list> to disconnect channels. Use SCAN <channel_list> to
scan (sequentially close) multiplexer channels.
Multiplexer Channel
Address For the RF multiplexers, the channel address (channel_list) is in the form:
•(@ccnn) for a single channel
•(@ccnn,ccnn) for multiple channels
•(@ccnn:ccnn) for sequential channels
•(@ccnn:ccnn,ccnn:ccnn) for groups of sequential channels
•or any combination of the above
where "cc" is the multiplexer card number (01-99) and "nn" is the channel
numbers (00-03 and 10-13).

Multiplexer Card
Numbers The multiplexer card number depends on the switchbox configuration
(single-module or multiple-module) set for the multiplexers. (Leading
zeroes can be ignored for the card number.) For a single-module switchbox,
the card number is always 01.
For a multiple-module switchbox, the card numbers are 01, 02,...,n. The
switch module with the lowest logical address is always card number 01.
The card number with the next successive logical address is card number 02,
and so on. See the Agilent B-size configuration guide for a definition of
logical addresses.
Example: Multiple-Module Switchbox Card Numbers
Assume the three multiplexers in the following figure form a
multiple-multiplexer switchbox instrument with multiplexer logical
addresses of 120, 121, and 122. Since card number 01 is assigned to the
module with the lowest logical address, etc., the card numbers are as shown.
Multiplexer Channel
Numbers RF multiplexer channel numbers are 00 through 03 and 10 through 13.
The channels can be addressed using channel numbers or channel ranges.
For a single-module switchbox, channel ranges can span across the two
channel banks. For multiple-module switchboxes, channel ranges can
span across the channels of all modules.

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 03and 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 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 BASIC as the
program language. The computer interfaces to the mainframe using the
General Purpose Interface Bus (GPIB)*.
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 Agilent 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
