8-50. General Commands
SCOPE
(IEEE-488, RS-232, Sequential)
Programs the 5520A-SC oscilloscope calibration hardware, if installed. The instrument
settings are determined by this command’s parameter. Once in SCOPE mode, use the
OUT command to program new output in all functions except Impedance Measurement
and the RANGE command as required (in OVERLD, PULSE, and MEAS Z functions
only.) OPER, STBY, *OPC, *OPC?, and *WAI all operate as described in Chapter 6.
The state of the oscilloscope’s output while in SCOPE mode is reflected by the bit in the
ISR that is assigned to SETTLED.
Table 8-15. SCOPE Command Parameters
Parameter Description/Example
OFF Turns the oscilloscope hardware off. Programs 0 V, 0 Hz, output at the NORMAL
terminals, standby.
VOLT Oscilloscope ac and dc VOLT mode. Programs 20 mV peak-to-peak, 1 kHz, output at
the SCOPE BNC, output impedance 1 MΩ, standby if from OFF or previously in
standby. FUNC? returns SACV (for ac) or SDCV (for dc).
Example: SCOPE VOLT; OUT 4 V, 1 kHz
(ac voltage, 4 V peak-to-peak, 1 kHz.)
EDGE Oscilloscope EDGE mode. Programs 25 mV peak-to-peak, 1 MHz, output at the
SCOPE BNC, standby if from OFF or previously in standby. FUNC? returns EDGE.
Example: SCOPE EDGE; OUT 0.5 V, 5 kHz
(Edge, 0.5 V peak-to-peak, 5 kHz.)
LEVSINE Oscilloscope LEVSINE mode. Programs 30 mV peak-to-peak, 50 kHz, output at the
SCOPE BNC, standby if from OFF or previously in standby. FUNC? returns LEVSINE.
Example: SCOPE LEVSINE; OUT 1 V, 50 kHz
(Leveled sine wave, 1 V peak-to-peak, 50 kHz.)
MARKER Oscilloscope MARKER mode. Programs the period to 1 ms, output at the SCOPE
BNC, standby if from OFF or previously in standby. FUNC? returns MARKER.
Example: SCOPE MARKER; OUT 2 MS
(Marker, period of 2 ms.)
WAVEGEN Oscilloscope WAVEGEN mode. Programs 20 mV peak-to-peak, square wave, 1 kHz,
no offset, output impedance 1 MΩ, standby if from OFF or previously in standby.
FUNC? returns WAVEGEN.
Example: SCOPE WAVEGEN; OUT 1 V, 1 kHz
(Wave Generator, 1 V peak-to-peak, 1 kHz.)
