5.9 Measurement Processing Section
・
Measurement time setting
Setting of time required for one measurement (in the case of sweep measurement, the
setting of the measurement time of not the entire sweep but of each point). Measurement
results are averaged within the range not exceeding the set time and the influence of
noise is reduced.
Setting range 0 ms to 9,990 s
Setting resolution 3 digits or 0.1 ms, whichever is the largest
The minimum measurement time is approximately the following
time depending on measurement frequency f.
f < 1.36 kHz: (1 / f) s
< 30 kHz: 0.8 ms to 1.5 ms
≤ 36 MHz: 0.5 ms
Remark A time longer than the minimum measurement time is required for
measurement regardless of the setting.
The measurement delay time and measurement start delay time
are not included. The time resulting from adding these delay times
to the measurement time setting will be the actual measurement
time.
The measurement time may become longer than the set time due to
auto ranging and other processing.
・
Measurement delay function This function delays the start of measurement after the
sweep parameters are changed.
Setting range 0 to 9,990 s
Setting resolution 3 digits or 0.1 ms, whichever is the largest
・
Measurement start delay function This function delays the start of measurement
only when sweeping starts.
Setting range 0 to 9,990 s or MANual
Setting resolution 3 digits or 0.1 ms, whichever is the largest
Remark MANual is a function for sequence measurement. For every
sequence, sweep measurement enters the wait state until the UP or
DOWN key is pressed.
・
Automatic high density sweep (slow sweep)
When there is a sudden change in the measurement data during frequency sweep
measurement, this function performs measurement by automatically increasing the
frequency sweep density in the regions before and after that point. This function is
disabled when the sweep item is set to other than frequency. If the number of
measurement frequency points exceeds 20,000 in one sweep, sweep measurement is
