Specications of Input, Output, and Measurement
Specications of waveform recording
Number of channels
to be measured
Voltage and current waveforms: Up to 8 channels
(depending on the number of installed input modules; up
to 16 waveforms can be displayed, however.)
Motor waveform: Up to 4 analog DC channels + up to 8 pulse channels
Recording capacity (5 megawords)
×
[(Number of measured items, including voltage and current)
×
(Number of channels, up to 8) + (Number of motor waveforms)]
No memory segmentation function
Waveform resolution 16-bit (Top 16 bits are used for voltage and current waveforms from the U7005.)
Sampling speed Voltage and current waveforms: Always 15 MS/s
(For the U7001, 2.5 MS/s sampled data is interpolated
with 0th held.)
Motor waveform (Analog DC): Always 1 MS/s
(1 MS/s sampled data is interpolated with 0th held.)
Motor waveform (pulse): Always 15 MS/s
Compression ratio 1/1, 1/2, 1/3, 1/6, 1/15, 1/30, 1/60, 1/150, 1/300, 1/600, 1/1500
(15 MS/s, 7.5 MS/s, 5 MS/s, 2.5 MS/s, 1.0 MS/s, 500 kS/s, 250 kS/s,
100 kS/s, 50 kS/s, 25 kS/s, 10 kS/s)
However, compression ratios of 1 MS/s or less only are available for motor waveforms
(analog DC).
Recording length 1 kiloword, 5 kilowords, 10 kilowords, 50 kilowords, 100 kilowords, 500 kilowords,
1 megaword, 5 megawords
Storage mode Peak-to-peak compression
Trigger mode Single, normal (auto-trigger setting available)
Pre-trigger 0% to 100% of the recording length, in 10 percent points increments
Trigger detection
method
• Level trigger (detects triggers based on uctuations in the level of storage waveforms.)
Trigger source: Voltage and current waveforms, voltage and current waveforms
processed by the zero-cross lter, manual trigger, motor
waveform, motor pulse
Trigger slope: Rising edge, falling edge
Trigger level:
±
300% of the range for waveforms in 0.1 percent points
increments
