Microwave Switch Description
All three Microwave Switch modules provide switching of up to five
microwave coaxial switches or channels. The difference between the HP
E1368A Microwave Switch, the HP E1369A Microwave Switch Driver,
and the HP E1370A Microwave Switch/Attenuator Driver modules are
describ ed below:
• The HP E1368A Microwave Switch is a 3-channel, single-pole,
double-throw coaxial switch module. The three coaxial switches
provided have excellent electrical charact eristics for 502
transmission systems operating from DC to 18 GHz. Th e module
panels are numbered 00, 01, and 02 to indicate the channel number
of each coaxial switch i nstalled.
• The HP E1369A Microwave Switch Driver is identical to the HP
E1368A, except the coaxial switches are not installed. The module
panel has three cutouts and various mounting holes that allow the
user to install up to three 3-port, 4-port, or 5-port, 42Vpk drive level
coaxial switches. Drive level voltage can be internal (+5 and
+12Vdc) or external (42Vpk). The module panel is nu mbered 00,
01, and 02 to indicate the channel nu mber of each coaxial switch.
Channel 03 and 04 are not labeled on the panel. Up to five coaxial
switches can be controlled (e.g. three internal, two external; five
external; etc) using the 14-pin connect or.
• The HP E1370A Microwave Switch/Attenuator Driver is identical to
the HP E1369A, except the module panel and mounting holes have
been modified to allow th e user to install on e Singl e-pole,
Multi-throw Switch or one Step Att enuator. Because of the size of
the switches and the attenuators, the module takes up two B-size
slots. Driv e level vo ltage can be internal (+5 and +12Vdc) or
external (42Vpk). Up to a Single-pole, Six-throw Switch can be
mounted on to the assembly or used externally using the 14-pin
connector.

HP E1368A
Switches
The HP E1368A Microwave Switch module contains three HP 33311B
Option 011 (8672B Option 005 and 100) microwave Switches:
• Broad bandwidth (DC - 18 GHz).
• High isolation (>90 dB to 18 GHz).
• Excellent repeatabi lity (typically 0.03 dB after 1,000,000 s witchings).
• Internal 50Ω terminations.
These coaxial switches allow +5V coil voltage electrical chara cteristics
(drive volta ge) operation instead of the standard +24V. This is necessary
since the Microwave Switch module provides only +5V or +12V for driving
microwave switches.
These coaxial switches are break-before-make switches controlled by a
latching solenoid. Internal coil contacts open and remove coil voltage after
a switching op eration to minimiz e the amount of heat dissipated near the
swit ch contacts.
When a coil is energiz ed and a switching operation occurs, a pivot arm ature
in the microwave switch also operates both sets of contacts, either closing
the switch or connecting it to the 50Ω termination.

Instrument Definition
HP plug-in modules installed in an HP mainframe or used with an HP
command module are treated as independent instruments each having a
unique secondary HP-IB address. Each instrument is also assigned a
dedicated error queue, input and output buffers, status registers and, if
applicable, dedicated mainframe/command module memory space for
readings or data. An instrument may be composed of a single plug-in
module (such as a counter) or multiple plug-in modules (for a switchbox or
scannin g voltme ter instrument).
Programming the Microwave Switch
To program th e modules us ing SCPI commands, you must select the
controller Modu le language, interface address, and appr opria te commands.
See the HP 7 5000 Series B Install atio n and Getti ng Sta rted Guid e or t he
appropriate H P Command Module Manual for interface addressing and
controller language informat io n of Microwave Switch modul es in a
switchb ox or sca nning voltmeter con figuration.
Note This discussion applies to SCPI programming. See App endix B
(Microwave Switch Registers) for details on Microwave Switch modules
registers.
Selecting Channels: To address specific channels within a Microwave
Switch module in a switchbox, y ou must:
• send the appropriate SCPI comma nd str ing to the switch box (e.g.,
CLOSe, OPEN, etc.). For the Microwave Switch modules, use the
CLOSe command to connect the 2-port to the C-port. Use the OPEN
command to connect the 1-port to the C-port.
• specify the card number ( 01-99)
• specify the channel number (00-04)

Card Numbers The card number identifies the module within a switchbox. The Microwave
Switch card number depends on the switchbox confi guration (single-module
or multipl e-module) s et for the switches.
• Single-module. F or a s ingle-module s witch box, the card number is
always 01.
• Multiple-modul e. For a multiple-module switchbox, the switch
module with the lowest log ical addr ess is always card nu mb er 01.
The card number with the next successive logical address is 02, and
so on. Figure 1-2 i llustr at es the card numbers and logical a ddr e s s es
of a typical multiple-module switchbox.

HP 75000 Series B M a inframe (HP Model Number E1300/E1301) or in a
mainframe with a n HP E1405/E1406 Command Modul e. See the HP 75000

Command Module Manual for mor e information o n switc hbo xes and logical
addressing.
Figure 1-2. Card Numbers for Multip le-M odu le Swi tch box es
Channel Numbers The channel number identifies the channel within a module. The
Microwave Switch channel nu mber depends on the module (HP E1368A
Microwave Switch or HP E1369A Microwave Switch Driver).
• HP E1368A. Valid channel numbers are 00-04 (channels 03 and 04
are valid but not connected).
• HP E1369A. Valid channel numb ers are 00-04.
• HP E1370A. Valid channel numb ers are 00-04.
Channel Address For th e Microwave Switch Modules, the channel address (channel_list) is in
the form:
• (@ccnn) for a single channel
• (@ccnn, ccn n) for multiple channels
• (@ccnn:ccnn) for sequential channels
• (@ccnn:ccnn, ccnn:ccnn) for groups of sequential channels
• or any c omb ination of t he above
whe re "cc " i s the ca r d n umb er an d "nn " i s the chann el numb er . F o r
example, command string to close channel 02 of car d number 1 is:
CLOSe (@0102)
Since "cc" (the card number) must be sent, it becomes part of the channel
number. Also, you can ignore leading z eros i n the card numbers. Thus, to
close channel 02, s end "102" instead of "0102". To close the above channel,
execute:
CLOSe (@102)

SCPI Command
Format Used in
This Manual
Initial Operation
You can send SCPI commands in either sh ort or long f orm. Refer to
Chapter 4 for more informati on. A long form examp le is:
CLOSe (@102)
The same command shown without the lower case letters is the short form.
The command then becomes:
CLOS (@102)
Some commands in this manual are shown with brackets ([ ]). These are
implied or optional c ommands that you do not have to ex ecute. For
example, the
ROUTe command is an implied command and is shown in this
manual as:
[ROUT:]CLOS (@102)
Thus, to execute these commands, simply enter:
CLOS (@102)
Use the following program example to verify initial Microwave Switch
operation by closin g a channel and queryi ng channel c losure. Th e example
first resets the switchbox and then closes chann el 02 of a single Microwave
Switch module (card number 1) in the switchbox. The program next queries
the channel closure state. A returned "1 " shows that the comma nd to close
the channel has been sent to the switchbox. A return ed "0" shows that the
command to close t he channel has not been sent to the switchbox.

Warnings and Cautions
Chapter 2
Modules
Warning SHOCK HAZARD. Only service-trained personnel who are
aware of the hazards involved should install, remove, or
configure the Microwave Switch modules. Before you remove
any installed module, disconnect AC power from the mainframe
and from other modules that may be connected to the
Microwave Sw itch.
Caution MAXIMUM POWER. The maximum power that may be applied
to any SMA input connector is 1 W (CW). The maximum voltage
that may be applied to the EXTERNAL B+ terminal is 42Vpk.
CONNECTING +5V/+12V. For the Microwave Switch, the
mainframe backplane +5V is fused at 4A, and the +12V line at
4A. The tota l curre nt drawn by all coaxial sw itches conne cted
to the Microwave Switch module must not exceed the fuse
rating of the supplies (mainframe and/or external) used.
STATIC ELECTRICITY. Static electricity is a major cause of
component failure. To prevent damage to the e lectrical
components in the Micro wave Switch modules, observe
anti-static techniques whenever removing a module from the
mainframe or whenever working on a module.

Setting the Address Switch
The logical address switch (LADDR) factory setting is 120. You may have
changed the setting during module inst al lation. Valid address values are
from 0 to 255. If the Microwave Switch modules are used in a HP
E1300/E1301 Mainframe, refer to the HP 75000 Series B System
Installation an d Getting Start ed Guide for addressing information.
Otherwise, us e Figure 2-1 to c hange the setting.
Note The address switc h selec t ed valu e must b e a multiple of 8 if the module is
the first modu le in a " switchbox" us ed in a V X Ib us ma inframe, an d being
inst ru cted by SCPI comman ds.

Selecting the Interrupt Priority
The Microwave Switch modules genera t e interrupts after a channel has been
closed or opened. The se interrupts are sent to, and acknowledgments ar e
received from, the slot 0 module via the VXIbus backplane interrupt lines.
For most applications where the Microwave Switch modules are installed in
an HP 75000 Series B or Series C mainframe, these jumpers do not have to
be moved. This is because the VXIbus interrupt lines have th e same
priority a nd interrupt priority is estab lished by installing modules in slots
numer ically clos es t to the sl ot 0 m odu le. Thus, slot 1 (int ernal to the Series
B mainframe) has a higher priority than slot 2 (also internal), s lot 2 has a
higher priority than slot 3, etc.
Refer to Figure 2-2 t o c hange t he int errupt priority. You can sel ect seven
different interrupt priorit y le ve ls. Level 1 is the l owest priority an d Level 7
is the highest priority. The Module’s factory setting is Level 1. To change,
clip out and remove two jumpers from the old priority location. I nstall and
solder two n ew jumpers in the new priority loca t ion (Figure 2-2 shows a
priority change from 1 to 7).
Note Both jumper locati ons m ust have the same interrupt pr i ority level jump er

Installing Switches on the HP E1369A
Because the HP E1369A Microwave Switch modules do not have
Microwave Switches installed by the factory, it is necessary to install or
connect s witches before operating. Determine the nu mber of switches, and
whether the switches are to be installed on, or connected to, the module and

After selec t ing the coaxial switch, install as follows:
1. Position the coaxial switch beh ind th e channel 00 panel cut-out.
Secure to rear panel using two M2.5 x .45 metric screws
(P/N 0515-1373).
2. Route the 3-wire cable (P/N E1368-61601) from J1 to the coaxial
switch terminals. Solder th e "RED" wire to pin 1. Solder the "YEL"
wire to pin C. Solder the "ORN" wire to pin 2.
Note On the HP 33314 (8765) series switches, it is necessary to jumper the two C
terminals so that both connect to the "YEL" wire.
3. Repeat steps 1 and 2 with remaining coaxial switches. The chann el
01 switch connects to J2 connector, and channel 02 connects to J3.
Caution Do not leave an unused 3-wire cable installed in J1, J2, or J3 if
a coaxial switch is not installed. The center conductor of all
three connectors is connected to the switch operating voltage
at all times. Contact of this conductor to ground may cause the
fuse to open, or damage to the power supply or module.
4. Route the 3-wire cables behind the coaxial switches as not to catch or
snag on any o b jects dur ing module installation in the mainframe or
control module (see Figure 2-3).
5. Select correct switch o p erati ng voltages (see “Sel ecting Switch

Selecting Switch
Power
After the coaxial switches have been installed (refer to “Installing Switches
on the HP E1369A” earlier in this chapter), the correct o p erating voltage
mu s t be selected. See i nstalle d switch s pecifications.
The Microwave Switch modules are capabl e of providing +5V (set at
factory) or +12V using t he mainframe power supply, or external voltag es of
up to 42Vpk can be connected. Deter mine t he required operating voltage
and proceed as instr ucted below. Ref er to Figure 2-5 as required.
Caution MAXIMUM CURRENT. The maximum current that the control
circuit can accommodate is 1 amp per switch. Maximum
current also depend s on the output capacity of the mainframe
or power supply used.
Internal Power Verify that the F3 fuse (P/N 2110-071 2) is instal led. Position jump ers as
instructed:
• For 5V, jumper JM2 ins ta lle d, and jumper JM151 removed.
• For 12V, jumper JM151 installed, and j umper JM2 removed.
External Power Verify that the F3 fuse (P/N 2110-0712) is removed (unsolder if necessary).
Connect the positive lead to EXT B+ on TB1, and the negative lead to EXT
GND on TB1. Connect leads to external power supply. Observe polarity.
Caution MAXIMUM VOLTAGE. The maximum voltage that may be
applied to the EXTernal POWER terminal is 42Vpk.
• Maximum wire size is No. 16 AWG. Wire ends should be stripped 6
mm (~ 0.25 in.) and tinned to prevent single strands from shorting
adjac ent ter minals .
• It is recommended that eac h channel wire be identified (color coded
or marked) as the connection is not visible when the Microwave
Switch module is installed.
• Verify that wires make good connections on scre w term ina ls.
