Calibrating Generator - Quantum Data 701A Quick Start Manual

Model 700A and 701A generators use programmable hardware to set the amplitude calibration factors
for analog video outputs. These calibration factors are stored in Flash EPROM, and are not lost if the
batteries are run down or removed.
Quantum Data calibrates the analog video and sync output amplitudes in new generators to published
specifications. You can recalibrate these amplitudes over a nominal range to meet your specific testing
conditions.
