Abridged Command List xiii
SR620 Universal Time Interval Counter
GENA(?) j Turns graphs 0 = off, 1 = on.
GSCL(?) j,x Sets the graph scales. j = 0 = histogram verticalscale,j=1= histo
horizontal,j=2=histo bins,j=3= mean graph scale,j = 4= jitter graph scale. x =
units per division or # bins.
PDEV(?) j Sets output device to 0 = printer, 1= plotter.
PLAD(?) j Sets the plotter GPIB address.
PLPT(?) j Sets the plotter port to 0= RS232 , 1= GPIB.
PLOT Initiates a print/plot
PCLR Clears plots/prints
Front Panel Control
DISP(?) j
Sets the display source. 0=MEAN,1=REL,2=JITTER,3=MAX
4 =MIN, 5 = TRIG, 6 = DVM's
EXPD(?) j Set the x1000 expand status in freq and per mode 0 = off, 1 = on
KEYS(?) j Simulates a keypress, or reads the most recently pressed key
Rear Panel Control
CLCK(?) j
Sets the clock source. 0 = internal, 1= external.
CLKF(?) j Sets the external clock frequency. 0=10MHz,1= 5MHz.
PORT(?) j Sets/reads the binary I/O port when enabled.
PRTM(?) j Sets the printer port mode. 0 = print, 1 = input,2 =output.
RNGE(?) i{,j} Sets the full scale voltage of DVM input i.
VOLT? j Reads DVM channel 0 or 1.
Interface Control Commands
*RST
Clears instrument to default settings.
*IDN? Returns the device identification .
*OPC(?) Operation complete common synchronization command. Either sets a status
bit or returns a value when all operations (scans , prints, measurements) are
complete.
*WAI Wait synchronization command. Holds off further command execution until all
in progress operations (scans, prints,measurements) are complete.
ENDT {j,k,l,m} Sets the RS232 end transmission terminator
LOCL j Sets the RS232 local/remote function. 0 = local, 1=remote, 2 = local lockout
WAIT(?) j Sets the RS232 intercharacter time delay.
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'son 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.
EREN(?) j Sets/reads the error status enable register.
ERRS? {j} Reads the error status register, or just bit n of register.
STAT? {j} Reads the TIC status register, or just bit n of register.
TENA(?) j Sets/reads the TIC status enable register.
STUP? Returns the complete setup in one string.
Calibration Control (NOTE: these commands are not needed during normal operation)
$TAC? j
Reads the value of the time-to-amplitude converters.
$PHK? j Sets the printer handshake lines.
