4.3.2. Sampling Speed of Recording Device
There are three types of recording device (PRINTER, SSD, and MEMORY).
The sampling speed setting range and characteristics of each device are indicated below.
PRINTER
Setting range 100 ms/div (1 kS/s)
to 10 min/div (10 S/min)
Characteristics
Records the waveform to the long-term printer at low speed.
Because the waveform is directly recorded to the recording paper, it is
easy to confirm the input signal and suitable for viewing long-term trends.
The recorded data is internally sampled at 20 MS/s and the waveform is
recorded with P-P data, which enables recording of high-speed signals
without loss.
SSD
Setting range
100
μ
s/div (1 MS/s) to 10 min/div (10 S/min)
Characteristics
Records the long-term data to the SSD at medium speed.
NORMAL or P-P can be selected for the recorded data.
When recorded with NORMAL data, FFT or X-Y analysis is possible in
addition to standard Y-T waveforms.
For P-P data, the data can be recorded for extended periods at a speed
where the printer cannot record.
MEMORY
Setting range
5
μ
s/div (20 MS/s) to 10 min/div (10 S/min)
Characteristics
Records the data to the internal memory with high-speed sampling.
The data is recorded when the trigger conditions set in advance are
detected, and recording automatically ends when the specified sample
count has been recorded.
Only NORMAL can be selected for the recorded data.
This is suitable for sudden input signals, rise/fall time, and measurement of
the delay between signals.
4.3.3. NORMAL Sampling and P-P Sampling Data
This product has two data formats: NORMAL and P-P.
Normal Sampling
With normal sampling, the A/D value of the sampling period is recorded as data and used for waveform
reproduction and data analysis.
