FET Multiplexer Module Description

Chapter 1

The FET multiplexer module provides high-speed switching (multiplexing)
for up to 16 channels. The module can be used as a scanning multiplexer
for a scanning voltmeter configurat ion, or a s a st and-alone multiplexer in a
switchbox c onf igurat ion. The c hannels are numbered 00 to 15. Each
channel provides connections for High (H), Low (L) and Gua rd (G),
although only High and Low are switched. The FET multiplexer module
can switch up to 100,000 connections per second (100 K switches/sec).

The FET multip le xer module consists of a co mpo nent a s sembly and a
terminal module. There are three different terminal modules, one for each
of the following applications: HP E1351A 16-Chann el FET Multiplexer
Module, HP E1353A 16-Channel Thermocouple FET Multiplexer Module,
and HP E1352A 32-Cha nne l Single-Ended FET Mu ltip lexer Module. Th e
component assembly is the same for all three applications. For information
on the 32-Channel Single-Ended FET Multiplexer Module, see the
HP E1352A User’s Manual.

The component assembly contains the VXIbus interface, the FET switches,
the analog bus connector and the digital bus. The terminal modules prov ide
connection points for the individual channels, as well as monitoring points
for the tree terminals and the direct terminals. The FET multiplexer module
can be externally triggered from the VXIbus backplane or through the
digital bus handshake lines on the front of the component assembly.

Chapter 1 Gettin g Started with the HP E1351A/53A 11

For high-speed operation (100 K switches/sec.) the scanning list is
automatically downloaded into RAM on the multiplexer module.
Triggering for c hannel adva nce is from the two handshake lines on the
digital bus. The scanning operation does not require any intervention from
the mainframe CPU. This only applies for switchboxes or scanning
voltmeter configurations that have all FET multiplexer modules. For a
downloaded sca n list in switchboxes, the trigger source must be

TRIG:SOUR DBUS or TRIG :S OUR IM M.

Multimeter Connection Points

There are three places where signals on a closed channel can be measured:
analog bus connector, tree terminals and direct terminals. Each of these
pro v ide s a d ifferen t c a pab i li ty for con figuri ng the modu le .

Analog Bus

Connector

The analog bus connector provides a direct connection between multiple
multiplexer modules and also b etween a mult iplexer module and HP
E1326/E1411 Multimeters. A ribbon cable is used to daisy-chain multiple
multiplexer modules together, and to connect a multimeter to the
multiplexer modules for a scanning volt meter. The
command automatically closes the appropriate tree isolation switches to
route closed channels to the analog bus. This command must be executed in
a switchbox configuration. A scanning voltmeter automatically configures
the multiplexer for the analog bus connector.

SCAN:PORT ABUS

Tree Terminals Tree terminals provide an external connection point through the terminal

modules for the signals which are on the analog bus lines. Tree terminals
are the recommended connection points for connect ing stand-alone
multimet ers and externa l curr ent sources for 4-wire resistance
measurements.

Direct Terminals The 16 channels are s epara ted into two banks, Bank 0 and Bank 1. When a

channel is closed, that channel is connec ted to a Bank Common. Channels
00 to 07 are on Bank 0 Common and channels 08 to 15 are on Bank 1
Common. The terminal module has connection point s for t he direct
terminals, where you can measure signals on the respective Bank
Commons. The ban ks can be isolat ed from each other, from the analog bus
connector, and from the tree terminals with the A and B tree isolation
switches.

Switchbox and Scanning Voltmeter Configurations

A VXIbus instru ment is a modu le or group of modules which p erform a
specified fu nct ion. For the HP E1300/01 m a inframe, the first module in an
instrument must have a logical address which is evenly divisible by 8 (16,
24, 112), and the rest of the module s in t he ins tr ument are nu mbered
consecutively. The instrument’s secondary address is the whole number
equal to the logical address divided by 8 (for a logical address of 16, 17,
18,…23, the secon dary add r ess is 02). For instru ment definition in o ther
mainframes, s ee the mainfra me manual. If an instrument c onsists of onl y
multiplexer modules, it is a switchbox configuration. If a multiplexer
module(s) is comb ined with a mult imeter to form an instrument, that is a
scannin g voltme ter configurat ion.

Switchbox A switchbox is a multiplexer module or group of multiplexer modules

which form a single instrument. A switchbox can be connected to a
mu ltimeter whi ch i s a d iff erent V XIbu s in str umen t , t o a n HP-I B
multimeter, or to a stand-alone multimeter. The switchbox and the
multimeter have different secondary addresses. Separate configuration
commands m ust be sent to the switc hbox and to the multimet er. The
follo wing progra m illustrates the differe nt a ddre sses and the configuration
commands requ ired. The HP-IB interface select code is 7, and the
mainframe address is 09. The multiplexer has an instrument address of 24,
so its secondary address is 03. The multimeter is HP-IB controlled, and has
a primary ad dress of 22.

Digital Bus and Triggering

The HP E1351A/E1353 A can be trig gered f or channel advance from the
VXIbus backplane or through the digital bus handshake cable on the front
of the component assembly. Backplane triggering can come from HP-IB
comput er commands over the HP-IB Bus or from th e HP E1300/1301
Mainframe "Event In" port. Digital bus triggering uses two handshake
lines; channel advance and channel closed. Channel advance (input to
multiplexer) triggers an advanc e, and channel closed ( output from
multiple xer) signif ies a dva nce completed.

The HP E1326B Mu ltimeter has a digital bus port on t he face plate, and
connects to the multiplexer with th e digital bus cable (see Figures 2-10 and
2-11). To connect other multimeters for digital bus trigg ering, you must
prepare a custom cable. Use a connector like the one on the digital bus
cable (HP part nu mber E1300-61611 ). C onnect the measureme nt complete
port from the multimeter to the channel advance pin, and the external trigger
to the channel closed pin. Conn ect the grounds for both signals to the
digital bus ground (second pin from right). You can use this cable to
connect an external multimeter to a switchbox, and then use

(digital bus triggering). You can also order a custom cable with

DBUS

BNC to digital bus c onnectors, HP part number E1411-80001. See Figure
2-11 for more information on multiplexer-to-multiplexer and
multiplexer-to-multimeter connections.

Programming Language

The examples in this manual use the Standard Commands for
Programma b le I nstruments (SCPI) commands, H ewlett-Packard BASIC and
an HP 9000 Series 200/ 300 c omputer over the HP-IB. Chapter 5 contains
information on SCP I c ommand f orm at . Appendix B contains details o n the
registers f or regis t er-based programming.

Initial Operation

Use the following program to verify initial multiplexer operation by closing
a channel and querying channel closure. The computer interfaces to the
mainframe with the Hewlett-Packard Interface Bus (HP-IB). The HP-IB
interface select code is 7, and the mainframe address is 09. The multiplexer
has an instrume nt addre ss of 24, s o its seco ndar y ad dress is 03.

This example first resets the switchbox and then closes channel 02 of a
single multiplexer module (card number 1) in the switchbox. The program
next queries the channel closure state. A returned "1" shows that the
channel is closed, a returned "0" designates an open channel.

Warnings and Cautions

Warning SHOCK HAZARD. Only service-trained personnel who are

aware of the hazards involved should install, remove, or
configure the multiplexer modules. Before you install any
module, disconnect AC power from the mainframe and from
user wiring.

Caution MAXIMUM VOLTAG E/CU RRENT. The maximum volt age that

may be applied between High (H), Low (L), and Guard (G)
terminals is 15 V dc or 10.6 V rms (15 V peak). The maximum
current is 1 mA per channel.

STATIC ELECTRICITY. Static electricity is a major cause of
component failure. To prevent damage to the electrical
components in the multiplexer module, observe anti-static
techniques whenever removing a module from the mainframe
or whenever working on a module.

Chapter 2 Configuring the HP E1351A/53A FET Multiplexer Modules 17

Multiplexer Card Numbers

HP plug-in modules installed in an HP VXIbus mainframe are treated as
independent instruments each having a unique secondary HP-IB address.
An instrument may be composed of a single plug-in module or multiple
plug-in modu les. The card nu mber identifies the m odule w ithin a
switchbox or scanning voltmeter configuration. The multiplexer module
with the lowest logical addr ess is al ways card nu mber 01. The multiple x er
module with the next successive address is 02, and so on. Figure 2-1
illustrat es the card numbers and logical addresses o f typical single-module
switchb ox es. Figure 2-2 illustrates the card numbers and logical address es
of a typical multiple-module switchbox. Figure 2-3 illustrates the card
numbers and logical addresses of a typical multiple-module scanning voltmeter.

Connecting Field Wiring

Leads for the individual channels are connected through the channel
terminals on the terminal modules. Multimeters and signal generators can
be connected to the di rect terminals or tree terminals on the terminal
modules. Figure 2-9 shows the terminal module channel terminals for the
16-Channel FET Multiplexer Module (HP E1351A) and the 16-Channel
Thermocouple FET Multiplexer Module (HP E1353 A).

Wiring Guidelines • If possible, use shielded cables with the shields connected to the Guard

(G) terminals and to the low connection near the measurement point.

• Be sure the wires ma ke good connectio ns on t he screw terminals.

• For thermocouples, connect the Guard terminal to the

thermocouple’s shield lead and the low connection near the
measurement poi nt.

Selecting Channels

Individual channels within a module or multiple-module instrument are
selected with the

channel_list> commands. OPEN and CLOSe <channel_list> immedia tely

<

opens/clos es the specified channel. The
creates a scann ing list which can be downloaded into RAM on each module.

INITiate command clos es the first channel on th e scan lis t, and th e

The
selected trigger mode advances the rest of t he c hannels.

The FET Mul tiplexer M odule uses brea k-bef ore-make logic so th at a c losed
channel is open ed before the next channel is closed. O nly one channel can
be closed at any given time on the FET multiplexer. The only exception is

SCAN:MODE FRES (4-wire resistance measurements). You can,

in
however, have a channel closed on two different modules in the same
instrument.

Chapter 3 Using the HP E1351A/53A FET Multiplexer Modules 29

SCAN <channel_list> or OPEN and CLOSe

SCAN <channel_list> command

To address specific channels within a multiplexer module in a switchbox or
scannin g voltme ter configuration, you mus t send the appropriate SCPI
command string with a specified card number (cc) and channel number
(nn). The card number refers to the multiplexer module within a switchbox
or scanning voltmeter configuration. The multiplexer module with the
lowest logical address in a VXIbus instrument is card number 01, and the
next consecutively numbered multiplexer module is card number 02. If you
have more than one switchbox or scanning voltmeter configuration, the card
numbering s equence starts at 01 for eac h c onf igurat ion. A channel address
is, therefore, a four digit number (ccnn). For channel 07 on card 02 the
address is 0207. You can delete leading zeros, so 207 is also a valid
channel address. 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.

OPEN and CLOSe commands should only be used with th e

The
