Table 8-15. SCOPE Command Parameters (cont.)
Parameter Description/Example
VIDEO Oscilloscope VIDEO mode. Programs 100% output (1V p/p), line marker 10,
format NTSC. FUNC? returns VIDEO.
Examples: SCOPE VIDEO; OUT 90
(Video, 90% output)
SCOPE VIDEO; OUT -70
(Video, -70% output, inverse video)
PULSE Oscilloscope PULSE mode. Programs 100 ns pulse width, 1.000 µs period, 2.5 V
range. FUNC? returns PULSE.
Example: SCOPE PULSE; OUT 50 ns, 500 ns; RANGE TP8DB
(Pulse, 50 ns pulse width, 500 ns period, 1.5 V range)
MEASZ Oscilloscope Impedance/Capacitance measurement (MEAS Z) mode. Programs
50 Ω range. FUNC? returns MEASZ.
Example: SCOPE MEASZ; RANGE TZCAP
(MEAS Z mode, capacitance range)
OVERLD Oscilloscope Overload mode. Programs 5 V dc range. FUNC? returns OVERLD.
Example: SCOPE OVERLD; OUT 7 V; RANGE TOLAC
(Overload, 7 V output, ac range)
SCOPE?
(IEEE-488, RS-232, Sequential)
Returns the oscilloscope’s current mode of operation. Returns OFF if the oscilloscope is
off.
Parameter: (None)
Response: <character> (Returns OFF, VOLT, EDGE, LEVSINE, MARKER,
WAVEGEN, VIDEO, PULSE, MEASZ,or OVERLD.)
TRIG
(IEEE-488, RS-232, Overlapped)
Programs the oscilloscope’s trigger output BNC.
Parameters: OFF (Turns the trigger output off.)
DIV1 (Turns the trigger output on. Frequency is the same as the
signal at SCOPE output.)
DIV10 (Turns the trigger output on. Frequency is 1/10 of the
signal at SCOPE output.)
DIV100 (Turns the trigger output on. Frequency is 1/100 of the
signal at SCOPE output.)
Example: TRIG DIV10
