Safety
Considerations for
this Instrument

WARNING This product is a Safety Class I instrument (provided with a protective

earthing ground incorporated in the power cord). The mains plug shall only
be inserted in a socket outlet provided with a protective earth contact. Any
interruption of the protective conductor inside or outside of the product is
likely to make the product dangerous. Intentional interruption is
prohibited..

Whenever it is likely that the protection has been impaired, the instrument
must be made inoperative and be secured against any unintended operation.

If this instrument is to be energized via an autotransformer (for voltage
reduction), make sure the common terminal is connected to the earth
terminal of the power source.

If this product is not used as specified, the protection provided by the
equipment could be impaired. This product must be used in a normal
condition (in which all means for protection are intact ) only.

No operator serviceable parts in th is product. Refer servicing to qualified
personnel. To prevent electrical shock, do not remove covers.

Servicing instructions are for use by qualified personnel only. To avoid
electrical shock, do not perform any servicing unless you are qualified to do
so.

The opening of covers or removal of parts is likely to expose dangerous
voltages. Disconnect the product from all voltage sources while it is being
opened.

Adjustments descr ibed in the manua l are performed with power supplied to
the instrument while protective covers are removed. Energy available at
many points may, if contacted, result in personal injury.

The power cord is connected to internal capacitors that my remain live for
5 seconds after disconnecting the plug from its power supply.

For Continued protection against fire hazard, replace the line fuse(s) only
with 250 V fuse(s) or the same current rating and type (for example, normal
blow or time delay). Do not use r e paired fuses or short circu i ted fu seh ol d ers.

Control Annunciators

The letters and symbols at the top right corner of the display indicate these conditions:

•R indicates the Test Set is in remote mode. The Test Set can be put into the remote mode
by an external controller or by an IBASIC program runn ing on the bu ilt-in IBASIC con­troller.

•L indicates the Test Set has been addressed to Listen.

•T indicates the Test Set has been addressed to Talk.

•S indicates the Test Set has sent the Require Service message by setting the Service Re­quest (SRQ) bus line true.

•C indicates the Test Set is currently the Acti ve Controller on the bus.

•* indicates an IBASIC program+ is running.

•? indicates an IBASIC program is waiting for a user response.

•- indicates an IBASIC program is paused.

Remote Mode

In Remote mode all front panel keys are disabled (except for the LOCAL key, POWER switch, Volume
control and Squelch control). The LOCAL key is only disabled by the Local Lockout bus command. When
in Remote mode and addressed to Listen the Test Set responds to the Data, Remote, Local, Clear(SDC),

and Trigger messages. When the Test Set is in Remote mode, the “R” annunciator will be displayed in the
upper right corner of the display screen and triggering is set to the state it was last set to in Remote mode
(if no previous setting the default is FULL SETTling and REPetitive RETRiggering). When the Test Set is
being addressed to Listen or Talk the “L” or “T” annunciators will be displayed in the upper right corner of
the display screen.

Local Mode

In Local mode the Test Set’s front panel controls are fully operational. The Test Set uses FULL SETTling
and REPetitive RETRiggering in Local mode. When the Test Set is being addressed to Listen or Talk the
“L” or “T” annunciators will be displayed in the upper right corner of the display screen.

20

20

S:\HP8920B\Qkref_20-206\BOOK\CHAPTERS\remmodes.fb

Remote/Local Modes

Remote or Local Mode

When addressed to Talk in Remote or Local mode , the Test Set can issue the Data and Status Byte
messages and responds to the Take Control message. In addition the Test Set can issue the Service Request
Message (SRQ). Regardless of whether it is addressed to talk or listen, the Test Set will respond to the
Clear(DCL), Local Lockout, Clear Lockout/Set Local, and Abort messages.

Local To Remote Transitions

The Test Set switches from Local to Remote mode upon receipt of the Remote message (REN bus line true
and Test Set is addressed to listen). No instrument settings are changed by the transition from Local to
Remote mode, but triggering is set to the state it was last set to in Remote mode (if no previous setting the

default is FULL SETTling and REPetitive RETRiggering). The “R” annunciator in the upper right corner
of the display is turned on.

When the Test Set makes a transition from local to remote mode all currently active measurements are
flagged as invalid causing any currently available measurement results to become unavailable. If the
HP-IB trigger mode is RETR:REP then a new measurement cycle is started and measurement results will
be available for all active measurements when valid results have been obtained. If the HP-IB trigger mode
is RETR:SING then a measurement cycle must be started by issuing a trigger event.

Remote To Local Transitions

The Test Set switches from Remote to Local operation (full front panel control) upon receipt of the Local
message (Go To Local (GTL) bus message and Test Set is addressed to listen) or the Clear Lockout/Set
Local message (REN bus line false). No instrument settings are changed by the transition from Remote to
Local mode, but triggering is reset to FULL SETTling and REPetitive RETRiggering. The “R”
annunciator in the upper right corner of the display is turned off.

If it is not in Local Lockout mode the Test Set switches from Remote to Local mode whenever the front­panel LOCAL key is pressed.

If the Test Set was in Local Lockout mode when the Local message was received, front-panel control is
returned, but Local Lockout mode is not cleared. Unless the Test Set receives the Clear Lockout/Set Local
message, the Test Set will still be in Local Lockout mode the next time it goes to the Remote mode.

Local Lockout

The Local Lockout mode disables the front-panel LOCAL key and allows return to Local mode only by
commands from the System Controller (Clear Lockout/Set Local message).

When a data transmission to the Test Set is interrupted, which can happen if the LOCAL key is pressed, the
data being transmitted may be lost. This can leave the Test Set in an unknown state. The Local Lockout
mode prevents loss of data or system control due to someone unintentionally pressing front-panel keys.

21

S:\HP8920B\Qkref_20-206\BOOK\CHAPTERS\remmodes.fb

Remote/Local Modes

NOTE: Return to Local mode can also be accomplished by setting the POWER switch to OFF and

back to ON. However, returning to Local mode in this way has the following
disadvantages:

1 It defeats the purpose of the Local Lockout mode in that the Active Controller will loose

control of the Test Set,.

2 Instrument configuration is r eset to the power up condition thereby loosing the instru-

ment configuration set by the Active Controller

Clear Lockout/Set Local

The Test Set returns to Local mode (full front panel control) when it receives the Clear Lockout/Set Local
message. No instrument settings are changed by the transition from Remote mode with Local Lockout to
Local mode but triggering is reset to FULL SETTling and REPetitive RETRiggering.

HP-IB Command Syntax Listings

Command Listing Conventions

Command listings are used to define the Test Set’s HP-IB commands. The listing shows the commands,
their hierarchical relationships, related parameters (if any), and associated notes (if any).

The Test Set’s commands are based upon a hierarchical structure, also known as a tree system. In such a
system, associated commands are grouped together under a common node in the hierarchy, analogous to
the way leaves at a same level are connected at a common branch. This and similar branches are connected
to fewer and thicker branches, until they meet at the root of the tree. The closer to the root, the higher a
node is considered in the hierarchy.

The command listing is divided into columns, as indicated by light gray vertical lines. The root node is the
leftmost column. Lower nodes in the hierarchy are indented one position to the right, below the root node.
To obtain a particular command, the full path to it must be specified. For example: to set the low side of the
audio input on the Audio Analyzer to float you would generate the following command:

:AFANalyzer: AI N ’Float’

:AFANalyzer

:AIN ’Gnd’

’Float’
’600 to Hi’

:AIN? (Returns quoted string)

:ELResistor (See Real Number Setting Syntax, :STATe not included)

Directs the user to a specific Instrument Command,
Measurement Command, or Number Setting Command
syntax listing.
Notes indicate which, if any, Number Setting Commands are
not supported by this particular path.

Square brackets([]) are used to enclose a keyword that is optional when programming the command; that
is, the Test Set will process the command to have the same effect whether the option keyword is omitted by
the programmer or not.

Letter case (uppercase or lowercase) in listings is used to differentiate between the accepted short form (the
uppercase characters) and the long form (the whole keyword). The Test Set accepts only the exact short
and the exact long forms. Sending a keyword that is not the exact short form or the exact long form will
generate an error.

In the parameter section of the listing a number of characters have special significance. Square brackets
([]) are used to enclose one or more parameters that are optional when controlling the Test Set. Braces({}),
or curly brackets, are used to enclose one or more parameters that may be included zero or more times. The
vertical bar (|) can be read as “or” and is used to separate alternative parameter options.

The query form of a command is generated by appending a question mark to the last keyword. However,
not all commands have a query form, and some commands exist only in the query form. The listings
include, where applicable, the command form and the query form of each command.

HP-IB Command Syntax Listings

CAUTION: When changing a field’s setting, a space must always precede the settin g value in the

command string, regardless of the field type. For example:

:RFG:FREQ<sp ace>850MHZ
:EFG:ATT<SPA CE>’On’

Improper punctuation will result in the following error :

HP-IB Error: -102 Syntax Error.
