5.7 Measured Signal Control Section
・
Signal output control
Measurement synchronous drive
SYNC(AC+DC) The measurement signal and DC bias are turned on at the start of
measurement and turned off at the end of measurement.
SYNC(AC) The measurement signal is turned on at the start of measurement
and turned off at the end of measurement. The DC bias does not
change.
ASYNC The measurement signal and DC bias are not changed at the start
of measurement and end of measurement.
ON/OFF mode
QUICK The measurement signal amplitude and DC bias changes
immediately.
SLOW Output changes gradually over a period of approximately 10
seconds.
0° SYNC This instrument waits until the measurement signal phase
becomes 0° and then output turns off
Remark Regardless of the setting, output always turns on at phase 0°.
Frequency change mode
ASYNC The frequency changes immediately.
0° SYNC The frequency changes when the measurement signal phase
becomes 0°.
Remark The phase of the measurement signal is the phase at the signal
source inside this instrument. It may differ from the phase of the
signal applied to the DUT.
・
Sweep
Sweep item One of frequency, measurement signal amplitude, DC bias, and
time (zero span)
Sweep type Either linear or log
Log can be set only when the sweep item is frequency or
measurement signal amplitude.
Sweep control SWEEP UP: Sweeps in the direction of lower limit → upper
limit.
SWEEP DOWN: Sweeps in the direction of upper limit → lower
limit.
SPOT: Measures with fixed frequency, measurement
signal amplitude, and bias.
REPEAT: Repeats SWEEP or SPOT when turns on.
