Abridged Command List
Syntax
Variables i,j are integers. Variable x is a real number in integer, real, or exponential notation.
Commands which may be queried have a in parentheses () after the mnemonic. The ( ) are not sent.
Commands that may only be queried have a '' after the mnemonic. Commands which may not be queried
have no ''. Optional parameters are enclosed by {}.
Function Output Control Commands
AECL
AMPL() x
ATTL
FREQ() x
FUNC() i
INVT()i
KEYS() i
OFFS()x
SYNC() i
TERM() i
Sets the output amplitude/offset to ECL levels (1Vpp, -1.3V offset).
Sets the output amplitude to x. x is a value plus units indicator. The units can
be VP (Vpp), VR (Vrms). Example: AMPL 1.00VR sets 1.00 Vrms.
Sets the output amplitude/offset to TTL levels (5 Vpp, 2.5 V offset).
Sets the output frequency to x Hz.
Sets the output function. 0 = sine, 1 = square, 2 = triangle, 3 = ramp,
4 = noise.
Sets the output inversion on (i=1) or off (i=0). Used with the ramp function.
Simulates a key press or reads the most recently pressed key.
Sets the output offset to x volts.
Turns the Sync output on (i=1) or off (i=0).
Sets the output source impedance to 50Ω (i=0), Hi-Z (i=1).
Sweep control commands
FSEN() i
*TRG
SDIR()i
SPFR() x
SRAT() x
STFR() x
STYP() i
SWEN() i
TSRC() i
Enables FSK on (i=1) or off (i=0). Valid only if SDIR2 is sent first.
Triggers single sweeps if in single trigger mode.
Sets the sweep direction 0 = Ramp, 1 = Triangle, 2 = FSK.
Sets the sweep stop frequency to x Hz.
Sets the sweep rate to x Hz.
Sets the sweep start frequency to x Hz.
Sets the sweep type. 0 = linear sweep, 1 = logarithmic sweep.
Turns sweeps on (i=1) or off (i=0).
Sets the trigger source for sweeps. 0 = single, 1 = internal sweep rate.
Setup Control Commands
*IDN
Returns the device identification.
*RCL i Recalls stored setting i.
*RST
Clears instrument to default settings.
*SAV i Stores the current settings in storage location i.
Status Reporting Commands
*CLS
*ESE() j
*ESR {j}
*PSC() j
*SRE() j
*STB {j}
STAT {j}
DENA() j
Clears all status registers.
Sets/reads the standard status byte enable register.
Reads the standard status register, or just bit j of register.
Sets the power on status clear bit. This allows SRQ's on power up if desired.
Sets/reads the serial poll enable register.
Reads the serial poll register, or just bit n of register.
Reads the DDS status register, or just bit n of register.
Sets/reads the DDS status enable register.
