SLOPE/WIDTH Control — The small knob controls
the slope of the trapezoidal waveforms. The large
knob controls the time symmetry of the waveform.
The setting of these controls does not affect the other
waveforms. See Figure 2-2 for the sync signal relation-
ship.
WAVEFORM Selector — This control selects the wave-
form that appears at the 50Q output connector. The
waveforms are sine My , triangle ^ ,Square "M ;
positive going rectangular pulse ES , negative going
rectangular pulse ][ , trapezoidal AL, , positive
going trapezoidal pulse , negative going trape-
zoidal pulse 4, „and DC voltage.
OUTPUT ATTEN (dB) Control — The large knob
attenuates the 5002 output from 0 dB (10 V p-p max
into 5022 load) to —60 dB (10 mV p-p into 50€2) in
10 dB steps. LO and HI indicate the correct output
connector to use. The small VARIABLE knob may
be used to continuously change the amplitude by
approximately 20 dB. Maximum attenuation is —80 dB
(1.0 mV p-p into 509). The OUTPUT ATTEN (dB)
VARIABLE control is inoperative when DC is selected
on the WAVEFORM selector.
5082 OUT (HI) — This is the selected waveform
