DESCRIPTION OF INSTRUMENT The 067-0587-02 Signal Standardizer is a calibration aid for all 7000-series mainframes. It will standardize all mainframes to all 7-series plug-in units, both vertical and horizontal. Test functions permit calibration of deflection factor, transient response, and gain of trigger channels. Bandwidth measurements of mainframes alone can be made by connecting a frequency standard to the AUX IN-CW IN connector. The gain of the horizontal channel can be calibrated by applying a signal from a time-mark generator to the AUX IN-CW IN connector with the TEST selector set to AUX IN.
