Abridged Command List
x
LDWF? i,j
Allows downloading a j point arbitrary waveform of format i. i = 0 = point format, i= 1 =
vector format. After execution of this query the DS345 will return the ascii value 1. The
binary waveform data may now be downloaded.
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
Clears all status registers.
*ESE(?) j
Sets/reads the standard status byte enable register.
*ESR? {j}
Reads the standard status register, or just bit j of register.
*PSC(?) j
Sets the power on status clear bit. This allows SRQ's on power up if desired.
*SRE(?) j
Sets/reads the serial poll enable register.
*STB? {j}
Reads the serial poll register, or just bit n of register.
STAT? {j}
Reads the DDS status register, or just bit n of register.
DENA(?) j
Sets/reads the DDS status enable register.
Hardware Test and Calibration Control
*CAL?
Starts autocal and returns status when done.
*TST?
Starts self-test and returns status when done.
