Introduction
The 5500A-SC600 Option (the SC600 Option) provides functions that help you maintain
your oscilloscope’s accuracy by verifying and calibrating the following oscilloscope
characteristics:
•
Vertical deflection characteristics are calibrated and verified. The VOLT function
lets you compare the voltage gain to the graticule lines on the oscilloscope.
•
Pulse transient response is checked and calibrated, verifying the accuracy of the
oscilloscope’s measurement of pulse transitions using the EDGE function. Also, the
calibrator supports even faster pulse response checks using an external tunnel diode
pulser.
•
Frequency response is checked by verifying the bandwidth using the Leveled Sine
Wave (LEVSINE) function. Vertical deflection is monitored until the -3 dB point is
observed on the oscilloscope.
•
Horizontal (time base) deflection characteristics are calibrated and verified using the
Time MARKER function. This calibration procedure is similar to the one for
verifying the vertical deflection characteristics, except that it checks the horizontal
axis.
•
The oscilloscope’s ability to display, capture, and measure pulse width is checked
using the PULSE function. This function allows you to vary both the pulse width and
the period.
•
The oscilloscope’s ability to trigger on different waveforms is checked using the
Wave Generator (WAVEGEN) function.
•
The oscilloscope’s ability to trigger on and capture complex TV Trigger signals is
checked using the VIDEO function.
•
The oscilloscope’s input characteristics can be measured using the Input Resistance
and Capacitance (MEAS Z) function.
•
The oscilloscope’s input protection circuit can be tested using the Overload
(OVERLD) function.
The menus that implement these functions also include parameters for altering the way
the output signal responds to voltage, frequency, and time settings, giving you control of
the signal during calibration, and providing more methods for observing the signal’s
characteristics.
SC600 Oscilloscope Calibration Option Specifications
These specifications apply only to the SC600 Option. General specifications that apply to
the 5522A (the Calibrator) can be found in Chapter 1. The specifications are valid under
the following conditions:
•
The Calibrator is operated under the conditions specified in Chapter 1.
•
The Calibrator has completed a warm-up period of at least twice the length of time
the calibrator was powered off, up to a maximum of 30 minutes.
•
The SC600 Option has been active longer than 5 minutes.
