Set the output to ON.
Note 1: When output was turned off, the actual DATA,
DATA, CLOCK 1, CLOCK 1, 1/4 DATA, and 1/4
CLOCK output amplitude becomes 0Vp-p, and the
offset becomes 0V.
Note 2: Since the output circuit is not opened even when the
output is turned off, do not apply an external voltage
to the output terminals of this instrument.
Set the clock delay.
CAUTION
Life time of phase shifters:
This equipment uses built-in phase shifters, whose average life time is as fol-
lows.
Number of shifting times at -500 ps to +500 ps full scale: 100 thousands times
4.3.3 Duty adjustment
Fine adjustment of the CLOCK1/CLOCK1 duty can be done using the control on the side of the instrument. The duty
depends on the frequency, If the frequency is changed, monitor the waveform by sampling etc. and measure the duty again.
4.3.4 Cross point adjustment
Fine adjustment of the DATA,DATA cross point can be done using the control on the rear of the instrument.
