The three coaxial switches provided have excellent electrical characteristics for 502 transmission systems operating from DC to 18 GHz. The module panels are numbered 00, 01, and 02 to indicate the channel number of each coaxial switch installed.

∙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 numbered 00, 01, and 02 to indicate the channel number 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 connector.

∙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 the user to install one Single-pole, Multi-throw Switch or one Step Attenuator. Because of the size of the switches and the attenuators, the module takes up two B-size slots. Drive level voltage 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.

Power Supply

Circuit

Power to operate the coaxial switches can be supplied internally or externally, dependent on the type of coaxial switch used.

∙Internal voltages of either +5V or +12V can be selected using jumpers on the board. These voltages are routed through the module from the mainframe backplane.

Note Check mainframe power availability before using internal voltages.

∙External voltages of up to 42Vpk can be connected using the EXTernal POWER terminal block.

Caution

HP E1368A

Switches

MAXIMUM VOLTAGE. The maximum voltage that may be applied to the EXTernal POWER terminal is 42Vpk. Remove the F3 fuse when using external switch power.

MAXIMUM CURRENT. The maximum current that the control circuit can accommodate is 1 amp per switch. Maximum current also depends on the output capacity of the mainframe or power supply used.

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 repeatability (typically 0.03 dB after 1,000,000 switchings).

∙Internal 50Ω terminations.

These coaxial switches allow +5V coil voltage electrical characteristics (drive voltage) 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 operation to minimize the amount of heat dissipated near the switch contacts.

When a coil is energized and a switching operation occurs, a pivot armature 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 scanning voltmeter instrument).

Programming the Microwave Switch

To program the modules using SCPI commands, you must select the controller Module language, interface address, and appropriate commands. See the HP 75000 Series B Installation and Getting Started Guide or the appropriate HP Command Module Manual for interface addressing and controller language information of Microwave Switch modules in a switchbox or scanning voltmeter configuration.

Note This discussion applies to SCPI programming. See Appendix 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, you must:

∙send the appropriate SCPI command string to the switchbox (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)	= channel_list
	∙ 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 configuration (single-module or multiple-module) set for the switches.

∙Single-module. For a single-module switchbox, the card number is always 01.

∙Multiple-module. For a multiple-module switchbox, the switch module with the lowest logical address is always card number 01. The card number with the next successive logical address is 02, and so on. Figure 1-2 illustrates the card numbers and logical addresses of a typical multiple-module switchbox.

14 Getting Started with the HP E1368A/69A/70A

Chapter 1

The logical addresses noted in Figure 1-2 apply to modules installed in an HP 75000 Series B Mainframe (HP Model Number E1300/E1301) or in a mainframe with an HP E1405/E1406 Command Module. See the HP 75000 Series B Installation and Getting Started Guide or the appropriate HP Command Module Manual for more information on switchboxes and logical addressing.

Figure 1-2. Card Numbers for Multiple-Module Switchboxes

Channel Numbers The channel number identifies the channel within a module. The Microwave Switch channel number 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 numbers are 00-04.

∙HP E1370A. Valid channel numbers are 00-04.

Channel Address For the Microwave Switch Modules, 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 card number and "nn" is the channel number. For example, command string to close channel 02 of card 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 zeros in the card numbers. Thus, to close channel 02, send "102" instead of "0102". To close the above channel, execute:

CLOSe (@102)

Chapter 1

SCPI Command

Format Used in

This Manual

You can send SCPI commands in either short or long form. Refer to Chapter 4 for more information. A long form example 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 commands that you do not have to execute. 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)

Initial Operation

Use the following program example to verify initial Microwave Switch operation by closing a channel and querying channel closure. The example first resets the switchbox and then closes channel 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 command to close the channel has been sent to the switchbox. A returned "0" shows that the command to close the channel has not been sent to the switchbox.

The computer used in the example is an HP Series 200/300 computer with HP BASIC as the program language. The computer interfaces to the mainframe using the Hewlett-Packard Interface Bus (HP-IB).* The HP-IB interface select code is 7, the HP-IB primary address is 09, and the HP-IB secondary address is 15. Refer to the HP 75000 Series B Installation and Getting Started Guide for addressing information.

Example: Reset the switchbox and close channel 02.

10 OUTPUT 70915;"*RST"	!Resets the module; opens all
	channels.
20 OUTPUT 70915;"CLOS (@102)"	!Close channel 02.
30 OUTPUT 70915;"CLOS? (@102)"	!Query channel 02.
40 ENTER 70915;Value	!Enter results into value.
50 PRINT Value	!Display results (should return
	"1").
60 END	!Terminate program.

Warnings and Cautions

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 Switch.

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 total current drawn by all coaxial switches connected 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 electrical components in the Microwave Switch modules, observe anti-static techniques whenever removing a module from the mainframe or whenever working on a module.

Chapter 2

Configuring the HP E1368A/69A/70A Modules 17

Setting the Address Switch

The logical address switch (LADDR) factory setting is 120. You may have changed the setting during module installation. 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 and Getting Started Guide for addressing information. Otherwise, use Figure 2-1 to change the setting.

Note The address switch selected value must be a multiple of 8 if the module is the first module in a "switchbox" used in a VXIbus mainframe, and being instructed by SCPI commands.

Figure 2-1. Logical Address Selection

18 Configuring the HP E1368A/69A/70A Modules

Chapter 2

Selecting the Interrupt Priority

The Microwave Switch modules generate interrupts after a channel has been closed or opened. These interrupts are sent to, and acknowledgments are 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 the same priority and interrupt priority is established by installing modules in slots numerically closest to the slot 0 module. Thus, slot 1 (internal to the Series B mainframe) has a higher priority than slot 2 (also internal), slot 2 has a higher priority than slot 3, etc.

Refer to Figure 2-2 to change the interrupt priority. You can select seven different interrupt priority levels. Level 1 is the lowest priority and 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. Install and solder two new jumpers in the new priority location (Figure 2-2 shows a priority change from 1 to 7).

Note Both jumper locations must have the same interrupt priority level jumper installed. Changing the priority level jumpers is not recommended. Do not change unless specifically instructed to do so.

NOTE:

In this example, the priority jumpers are moved from position 1 to position 7 (lowest priority to highest priority).

Note

Because the HP E1369A Microwave Switch modules do not have Microwave Switches installed by the factory, it is necessary to install or connect switches before operating. Determine the number of switches, and whether the switches are to be installed on, or connected to, the module and proceed as instructed below.

Installation described for up to three coaxial switches (channels 00-02) is below. Figure 2-3 shows the wiring diagram and mounting hole centers for each switch installed.

HP SWITCHES. The following 5V HP 333XX series and HP 876X series switches will function in the HP E1369A Microwave Switch module.

The corresponding HP 876X and 333XX series switches shown in the table below are electrically and physically identical. The HP 8761, 8766 (33363), 8767 (33364),8768 (33365),8769 (33366) series coaxial switches will not function in the HP E1369A Microwave Switch module because the switch coils are not split (separate for each contact).

NON-HP SWITCHES. K&L Microwave Inc., Dynatech Microwave Technology Inc., and RLC Electronics Inc. currently manufacture split coil coaxial switches that will physically mount in the HP E1369A Microwave Switch module rear panel. All switches mount using the "A" hole centers (see Figure 2-3). When selecting switches, refer to the diagram shown in Figure 1-1 to verify that the switch will electrically function in the HP E1369A Microwave Switch module. Remember, switches must have split coil operation with 42V maximum drive level.

Caution The maximum current that the control circuit can accommodate is 1 amp per switch. Maximum current also depends on the output capacity of the mainframe or power supply used.

20 Configuring the HP E1368A/69A/70A Modules

Chapter 2

After selecting the coaxial switch, install as follows:

1.Position the coaxial switch behind the 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 the "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 channel 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 objects during module installation in the mainframe or control module (see Figure 2-3).

5.Select correct switch operating voltages (see “ Sele cting Switch Power” later in this chapter).

Power

After the coaxial switches have been installed (refer to “ Installing Switches on the HP E1369A” earlier in this chapter), the correct operating voltage must be selected. See installed switch specifications.

The Microwave Switch modules are capable of providing +5V (set at factory) or +12V using the mainframe power supply, or external voltages of up to 42Vpk can be connected. Determine the required operating voltage and proceed as instructed below. Refer 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 depends on the output capacity of the mainframe or power supply used.

Internal Power Verify that the F3 fuse (P/N 2110-0712) is installed. Position jumpers as instructed:

∙For 5V, jumper JM2 installed, and jumper JM151 removed.

∙For 12V, jumper JM151 installed, and jumper 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 adjacent terminals.

∙It is recommended that each 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 screw terminals.
