1710J-Series Waveform Monitors
Description
Backporch (J500 on/off)
Slow — 20% or less
Fast — 90% or greater
Attenuation of 60 Hz on input signal (J399 Fast/Slow)
APL changes from 50% to either 10% or 90% will cause blanking level shift of 1 IRE
unit [7.14 mV] or less
1 IRE unit [7.14 mV] or less shift from no color burst to presence of color burst
Description
100 kHz, 100 Hz, Synchronizes in 2H and 1H sweeps
Crystal controlled; timing accuracy is 10 s, 0.01 s, Can be used as 10 s and
1 s timing calibrator
140 IRE [1 V] within 1%
Top of waveform must be between 80 IRE (0.86 V) and 120 IRE [1.14 V] on graticule
when backporch is positioned to 0 IRE [0.300 V] line, with DC RESTORER on
Description
Sweep will occur in all Horizontal mode settings with or without synchronization
Equal to frame rate of applied video or external sync
Approximately X25
Equal to line rate of applied video or external sync
Equal to half line rate of applied video or external sync
2 LINE and 2 FLD sweep length is nominally 12.5 divisions
1 s/division 2%
0.2 s/division 3%
All timing and linearity specifications exclude the first and last major divisions of the
unmagnified display
