Controlling the Calibrator Signal
For verification purposes, the Calibrator Output signal can be manually con-
trolled. This includes changing its amplitude and frequency. The signal has the
following characteristics:
The signal’s amplitude can be set to one of five positions: 0 through 4. Zero
represents the smallest available amplitude. Four represents the largest
amplitude. These settings do not correlate to any specific amplitude and may
vary between instruments.
Shape square wave
Frequency 153 Hz to 5 MHz
Amplitude 5 positions
