WFM 1125 Option 0A/0B/0C/0D Service Manual
Tables 1–1 through 1–20 list the electrical specifications for the WFM 1125
Digital Television Waveform Monitor Option 0A/0B/0C/0D Option
0A/0B/0C/0D. Performance requirements are generally quantitative and can be
tested by qualified service personnel. Reference information describes useful
operating parameters and typical characteristics and performance.
The performance requirements listed in the electrical specification portion of
these specifications apply over an ambient temperature range of 0° C to +40° C.
The rated accuracies are valid when the instrument is calibrated at an ambient
temperature range of +20° C to +30° C, after a warm-up time of 20 minutes.
Performance requirements
