SC300 Oscilloscope Calibration Option Specifications
These specifications apply only to the SC300 Oscilloscope Calibration Option. General
specifications that apply to the 5502A Calibrator can be found in Chapter 1. The
specifications are correct given the 5502A is operated with the conditions specified in
Chapter 1, and has completed a warm-up period of no less than two times the length of
time the Calibrator was powered off, to a maximum of 30 minutes.

[1] The square wave signal into 1 M
Ω
is a positive square wave from 1.8 mV to 55 V p-p. From 95 V to 105 V, its output is a
square wave-like signal that alternates between the negative peak and the positive peak, with the centerline at
−
10 V. Signals
between 55 V and 95 V p-p are not available.
[2] The uncertainty for 50
Ω
loads does not include the input impedance uncertainty of the oscilloscope. Square wave signals
below 4.5 mV p-p have an uncertainty of
±
(0.25% of output
+
200 µV).
[3] Signals from 95 to 105 V p-p have an uncertainty of 0.5% of output in the frequency range 100 Hz to 1 kHz. Typical
uncertainty is 1.5% of output for 95 V to 105 V p-p signals in the frequency range 10 Hz to 100 Hz, and 0.5% of output in the
frequency range 1 kHz to 10 kHz.
