Real time save function *supported in version 2.50 or later
The real time save function enables data to be saved to
the PC card while waveform is being measured. The
compressed waveform is displayed on the screen at real
time. This function is valid at the recorder and memory
function. Write to the PC card can be up to 1kS/s
(=100ms/DIV) for 16 channels, or up to 500S/s (200ms/
DIV) for 32 channels. With the real time save function,
data measured at the pre-determined sampling below the
maximum sampling can be saved to the PC card at any
time.
In addition, since the same data is compressed along the
time axis and displayed on the screen, you can check
how recording is going. Compressed data is saved to the
PC card for later retrieval.

Note: Saved at 16 channels for 100 ms/DIV, or at 32 channels otherwise.
Note: Maximum continuous recording time at MEM function, with time axis is 1 hour/DIV in REC function.
Note: Limit of maximum continuous recording time at MEM function is 208 days and 8 hours.
Storage data (MEM waveform) :
Save measurement data to the PC card at real time
Time axis setting(MEM): 100 ms/DIV to 5 minutes/DIV
(sampling frequency starting from 1 kS/s for 16 channels or from 500S/s for 32 channels)
Recording length setting (MEM): depending on free capacity of the PC card
Input waveform
Storage data (REC waveform) :
Save compressed data to the PC card after
measurement
Time axis setting(REC): 500 ms/DIV to 1 hour/DIV
(sampling frequency starting from 1 kS/s for 16 channels or from 500S/s
for 32 channels)
Recording length setting (REC): up to 1000 DIV (or up to 5000 DIV with
memory expansion)
Display data (REC waveform): compressed waveform is displayed on screen
Compressed data is saved temporarily in the internal memory.
However, display time axis of REC data is 2 steps later than that of MEM data. The maximum recording time that
can be set is determined by the free capacity of the PC card, and the time axis and recording length of MEM/REC.
Nevertheless, since the maximum recording length of REC is fixed at 1000 DIV, or 5000 DIV if there is memory
expansion, even if there is plenty of free capacity on the PC card, the recording time cannot exceed the value
determined by REC time axis multiplied by 1000 DIV.
Trigger functions capable of monitoring all 32 channels
For all of the measurement functions, including record and
memory recorder, triggers can be set on all 32 channels. In
addition to a simple level trigger based on comparison with a
single voltage value, the following trigger functions are also
available:
• Window trigger based on 2 voltage values
• Voltage drop trigger for AC power lines
• Level trigger based on rms values
• Cycle trigger monitoring the rising edge of a voltage
• Pattern trigger monitoring the Hi/Low condition of a logic signal
