6-85. SC300 Specifications

These specifications apply only to the SC300. General specifications that apply to the
Calibrator Mainframe can be found in Chapter 1. The specifications are valid providing
the Calibrator Mainframe is operated under the conditions specified in Chapter 1, and
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. All SC300 specifications apply to the end
of the cable (PN 945014) supplied with the Option.

positive peak, with the centerline at –10 V. Signals between 55 V and 95 V p-p are not available.

oscilloscope. Square wave signals below 4.5 mV p-p have an uncertainty of
200 µV). 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 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.
[3] From 95 V to 105 V, the output is a square wave-type signal that alternates between the negative
peak and the positive peak, with the centerline at –10 V. If the oscilloscope you are calibrating
requires a fixed period for the square wave's peak-to-peak amplitude, you may need to adjust the
Calibrator Mainframe's frequency output to accommodate for this waveform. For example, the
Fluke ScopeMeter® has a calibration point at 1 kHz (1 ms), 100 V, peak-to-peak. To output a
period of 1 ms at 100 V peak-to-peak, use a frequency of 356 Hz.
