Section 3 Programming; Commands; Command Functional Groups; Input/Output Control Commands - Tektronix PFG 5505 Instruction Manual

Programming
The instrument is controlled by the front panel keys
or via commands received from the controller. These
commands a re of three types:
• Setting commands - control instrument settings.
• Query/Operational - request data.
Operational - cause a particular action as soon as
c
the message unit is received over the G PIB interface.
When the instrument is in the remote state, it provides
a response or executes all commands as appropriate.
In the local state, only query/operational commands
are executed; setting and operational commands
generate error responses, since instrument functions
are under front panel control.
NOTE
The PFG 5105 and PFG 5505 each respond to
as
all commands a PFG 5105. No distinction is
made between the two instruments over the
GPIB bus.

Command Functional Groups

The following list of commands i s arranged by func­
tional group; some functional g roup lists are also
divided into sub-groups.

INPUT/OUTPUT CONTROL COMMANDS

AM ON j OFF
Enables/disables use of the signal applied to the
AM IN connector to amplitude-modulate the main
output signal.
AM?
Returns the amplitude modulation mode status.
Response: AM ON; , o r AM OFF;
FM ON j OFF
Enables/disables the use of a signal applied to the
VCO/FM IN connector to modulate the frequency
of the main output signal.
FM?
Return s the frequency modulation mode status.
Response: FM ON ;, or FM OFF;
OUTput ON I OFF
Connects/disconnects the main output signal to the
front-panel OUTPUT connector.
OUTput FLOAT
Disconnects the main output signal from the front
3-2
COMMAN DS
panel OUTPUT connector and terminates it into a
high impedance (floating).
OUTput?
Returns the output signal status (OUT ON ;, OUT
OFF;, or OUT FLOAT;).
Store/Recall
RECall < bufnum >
Changes the instrument front panel settings to those
recalled from the specified settings buffer (butnum).
Buffer O is a read-only buffer that contains the
power-on settings. Buffer numbers:
SEND? < bufnum > [, < bufnum > ] ...
Returns the stored settings from the specified buf­
fer(s) . Query response : STORE < num > : < binblk >
[, < num > : < binblk > ] ... ;
SEND? ALL
Returns the contents of all stored setting locations,
beginning with buffer 1. Response: STORE ALL:
< binblk > ... < binblk > ;
STORe <bufnum > [: <binblk > [, <bufnum >: <binblk >]] ...
Saves the current front panel settings in a specified
buffer(s) ( < butnum > ) for later recall. Buffer
read-only buffer that contains the power-on settings;
attempting to store settings in buffer
an error. Optionally stores the settings data defined
in binblk in the specified buffer. < bufnum > : 1 - 99.
STORe ALL: < binblk > .. . < binblk >
Sequentially stores each front panel setup defined
in binblk in a settings buffer, beginning with buffer 1 .
Function
FUNCtion SINE
Selects the sine waveform for output.
FUNCtion SQUare
Selects the square waveform for output.
FUNCtion TRIAngle
Selects the triangle waveform for output.
FUNCtion D C
Selects d e output a t the current value of the DC
parameter.
FUNCtion SPULSE
Selects the single pulse mode.
FUNCtion DPULSE
Selects the double pulse mode.
