Syntax Rules

Spaces Use at least one space between a command and a

parameter. Do not use spaces within a parameter, or within a number.

Multiple Parameters

Numeric Parameters

Case Sensitivity

Extra Parameters

Null Parameters

Expressions Do not use expressions as parameters. An

Units Accepted units in command parameters are:

When a command has more than one parameter, separate the parameters with commas. For example: "OUT 1 V, 100 HZ".

Parameters may have up to 255 significant figures. Exponents may range from -32000 to +32000. The useful range for 5720A programming is ± 2.2 E-308 to ± 1.8 E308.

All lower case letters are converted to upper case except in quoted strings.

Avoid using extra parameters. Too many parameters will cause a command error.

Null parameters will cause a command error (e.g., adjacent commas in "CLOCK 133700, ,071787").

example of an expression is "(4+2*13)".

Multipliers MA mega, or unit x 1,000,000)

K kilo, or unit x 1,000) M milli, or unit ÷ 1,000;

Multiple Commands

Terminators Terminators sent by the 5720A: LF with EOI.

Responses The responses described in the command table are

To combine commands in one statement, use a semicolon (;). For example, instead of using these two statements:

20 PRINT @3,"OUT 100 MV" ! Select 100 mV dc 30 PRINT @3,"OPER" ! Activate the output You can accomplish the same with this single line: 20 PRINT @3,"OUT 100 MV ; OPER"

Terminators received by the 5720A: LF or any character with EOI

correct for IEEE-488 remote control, and for serial remote control in "COMPUTER" mode. In serial remote control in "TERMINAL" mode, responses contain more descriptive text intended for an operator using a terminal interactively.

Command Summary by Function

Error Mode Commands

ADJOUT? Returns adjusted output magnitude and frequency. INCR Increments or decrements the output MULT Multiplies reference by a value and establishes the

product as a new reference. NEWREF Establishes a new reference. OFFSET Sets and enables or disables an offset. OFFSET? Returns the value of the present offset. OLDREF Sets the output to the present reference. OUT_ERR? Returns the UUT error computed by the 5720A. REFOUT? Returns the value of the present reference. SCALE Activates and deactivates scaling. SCALE? Returns scaling information. SCAL_ERR? Returns the scale error value if scaling is active.

Instrument Configuration Commands

BTYPE Selects an amplifier type for voltage or current

boost. BTYPE? Returns the amplifier types set for voltage and

current boost. CLOCK Sets the clock/calendar. CLOCK? Returns the setting of the clock/calendar. CUR_POST Selects active binding post for current output. CUR_POST? Returns active binding post for current output. EXTGUARD Opens and closes an internal connection. between

GUARD and LO. EXTSENSE Opens and closes an internal connection between

SENSE and OUTPUT. FORMAT Restores calibration constants and other

parameters to factory defaults. LIMIT Sets positive and negative output limits. LIMIT? Returns the programmed positive and negative

output limits.

Command Summary by Function (continued)

*LRN? Returns a list of commands that can duplicate

the present state. RANGE? Returns the present output range. RANGELCK Locks the present range, or selects autoranging.

Output Commands

BOOST Activates or deactivates an auxiliary amplifier. DBMOUT? Returns the output amplitude and frequency, but

in dBm if ac V. OPER Activates the 5720A output if it is in standby. OUT Sets the output and establishes a new reference

for error mode. OUT? Returns the output amplitude and frequency. PHASE Sets the phase shift of the phase output signal. PHASE? Returns the phase shift of the phase output

signal. PHASELCK Activates or deactivates phase locking to an

external signal. PHASESFT Activates or deactivates variable phase output. RCOMP Activates or deactivates two-wire compensation

circuitry. STBY Puts the 5720A in standby. VOUT? Returns the output amplitude in volts if the active

units are dBm. WBAND Activates or deactivates the Wideband AC

Module (Option 5700A-03).

General Functions

*CLS Clear; clears status registers, any service

request, and flags. ECHO? Echoes a string to the remote port. GAL Go to Alternate Language; enters Fluke 5100B

or 5200A emulation mode. *OPC Sets bit 0 in the ESR to 1 when pending

operations are complete.
