D.
Adjust the AMPL knob for the desired amplitude at the OUTPUT connector.
NOTE: For low level applications, pull the AMPL knob for -20 dB (10-to-1 reduction)
attenuation of the output signal.
E.
Pull and ad just the OFFSET knob for a DC offset in the output signal at the OUTPUT
connector. The signal duty cycle may be varied by rotating the DUTY
knob.
Pull it to
invert the dut y
cycle.
F.
There is a simultaneous output at the TTL/CMOS connector. This output will drive 1ogic
circuitry. TIL output leve! is fixed at >3 V. For CMOS circuitry operating from a
5-to-15 volt power supply, pull the TTL/CMOS knob and adjust the leve! to the desired
value.
Figure 5.1 shows the phase relationships
betw~en
the TTL/CMOS and OUTPUT signais.
