Introduction
The SC600 Oscilloscope Calibration Option (the SC600 Option) has functions that help
you keep your oscilloscope’s accuracy by verifying and calibrating the subsequent
oscilloscope qualities:
•
Vertical deflection qualities are calibrated and verified. The VOLT function lets you
compare the voltage gain to the graticule lines on the oscilloscope.
•
Pulse transient response is examined and calibrated, verifying the accuracy of the
measurement of pulse transitions of the oscilloscope with the EDGE function. Also,
the Calibrator lets you do faster pulse response checks with an external tunnel diode
pulser.
•
Frequency response is examined by verifying the bandwidth with the leveled sine
wave (LEVSINE) function. Vertical deflection is monitored until the -3 dB point is
seen on the oscilloscope.
•
Horizontal (time base) deflection qualities are calibrated and verified with the time
MARKER function. This calibration procedure is like the one for verifying the
vertical deflection qualities, but it examines the horizontal axis.
•
The oscilloscope can show, hold, and measure pulse width. This is examined with the
PULSE function. This function lets you to change the pulse width and the period.
•
The oscilloscope can trigger on different waveforms. This is done with the wave
generator (WAVEGEN) function.
•
The oscilloscope can trigger on and capture complex TV trigger signals. This is done
with the VIDEO function.
•
The input qualities of the oscilloscope can be measured with the Input resistance and
capacitance (MEAS Z) function.
•
You can verify the oscilloscope input protection circuit with the overload
(OVERLD) function.
The menus that implement these functions also include parameters to change how the
output signal reacts to voltage, frequency, and time settings. This gives you control of the
signal when you calibrate, and gives more methods to see signal qualities.
