CONV(?) {i} Set (query) constant voltage mode on (i=1) or off (i=0).
FREQ(?) {i} Set (query) drive frequency to 100Hz(0), 120Hz(1), 1kHz(2), 10kHz(3) or 100kHz(4).
MMOD(?) {i} Set (query) measurement mode to continuous (i=0) or triggered (i=1).
NAVG(?) {i} Set (query) number of measurements to be averaged from i=2 to i=10.
PMOD(?) {i} Set (query) parameter mode to Auto(0), R+Q(1), L+Q(2), C+D(3), or C+R(4).
RATE(?) {i} Set (query) measurement rate to Fast(0), Medium(1) or Slow(2).
RNGE(?) {i} Set (query) measurement range to 100kΩ(0), 6.4kΩ(1), 400Ω,(2) or 25Ω(3).
RNGH(?) {i} Set (query) range hold to enabled (i=1) or disabled (i=0).
VOLT(?) {x} Set (query) drive voltage to 0.1V ≤ x ≤ 1.00V with 0.05V resolution.
MEASUREMENT CONTROL
PREL(?) {x} Set (query) nominal parameter value for deviation and %deviation to x (Ω,F,H).
STRT Starts a measurement.
STOP Stops the current measurement.
*TRG Same as STRT.
MEASUREMENT RESULT
OUTF(?) {i} Set (query) the output format to verbose (0) or concise (1) ASCII, or verbose (2) or
concise (2) binary.
XALL? Returns major and minor parameters plus bin number.
XBIN? Returns bin number of current measurement.
XDLT? Returns deviation between major parameter and nominal value.
XMAJ? Returns value of the major parameter.
XMIN? Returns value of the minor parameter.
XPCT? Returns percent deviation between major parameter and nominal value.
BINNING
BCLR Clears nominal values and limits for all bins. All bins are closed.
BING(?) {i} Set (query) binning to enabled (i=1) or disabled (i=0).
BLIM(?) i,j {,x} Set (query) upper (i=0) or lower (i=1) limit of bin j (0-7) to x%.
BNOM(?) i {,x} Set nominal value of bin i to x.
SETUP CONTROL
*
IDN? Returns the SR715/720 identification string.
*
OPC(?) Set bit in Standard Event Status byte when measurement complete.
*
RCL i Recall setting i.
*
RST Reset unit to default configuration.
*SAV i Save current setup as setting i.
*WAI Wait until all measurements are completed before proceeding.
STATUS
*CLS Clear all status registers.
*ESE(?) {i} Set (query) the Standard Event Status Byte Enable register to value i (0-255).
*ESR? {i} Query Standard Status byte. If i is included, only bit i is queried.
*PSC(?) {i} Set (query) power-on status clear bit to clear (i=1) or maintain (i=0) status values.
*SRE(?) {i} Set (query) the Serial Poll Enable register to value i (0-255).
*STB? {i} Query Serial Poll status byte. If i is included, only bit i is queried.
