Realtime Print to the Built-in Printer
≡
For a description of this function, refer to page 1-14.

Function
The waveform (screen image data) is continuously printed to the built-in printer like a recorder.
Waveform to realtime print
All of the original waveforms displayed on the screen are realtime printed. If only the X-Y
waveform/zoom waveform is displayed (the original waveform is not displayed), then realtime
printing cannot be performed.
Valid time axis setting for realtime print and the paper feeding speed (chart
speed)
The time axis setting that allows for realtime print is between 500 ms/div and 100 ks/div with
the sample rate of 200 kS/s or less). The sample rate varies according to the record length even
with the same T/div setting. For details, refer to Appendix 1 “Relationship between the Time
Axis Setting, Sample Rate and Record Length.” In addition, the chart speed is automatically
determined according to the time axis setting as follows.
T/div

1 s/div
10 mm/s
2 s/div
5 mm/s

Chart speed = 10 mm
÷
(number of seconds in 1 div on the time axis)
Example The chart speed for 50 s/div is 10 mm
÷
50 s = 0.2 mm/s
Record time
Realtime print is carried out for the specified amount of time. The time is selected at the time
of execution with the
START/STOP
key. The following record length can be selected.
Continuous (continue printing until the acquisition is stopped with the
START/STOP
key),
10s, 20s, 30s, 40s, 50s, 1 min to 9 min, 10 min to 50 min, 1 hour to 6 hour, 12 hour, 1 day to 10
day
The record time that can be selected varies depending on the record length and the time axis
setting. The time displayed on the lower part of the “Log Start” soft key menu is the upper
limit of the available record times. If the desired time cannot be selected, you can do the
following.
• Decrease the sample rate with the T/div knob
• Set the record length to 1M or more
Setting the record length for realtime print : Record length
Prints the specified record length of data in realtime. This is specified before executing with
the “Log Start” soft key in the
ACQ
menu.
The time corresponding to the set record length is displayed at the lower part of the “Log Start”
soft key (for example, 3 12:34:56 is 3 days and 12 hours 34 minutes 56 seconds).
The record length that can be specified varies according to the T/div setting or the memory
option. For details, refer to Appendix 1 “Relationship between the Time Axis Setting, Sample
Rate and Record Length.”
Starting the realtime print
Following methods can be used to start the realtime print.
• Pressing the
START/STOP
key initiates the print. After printing for the set time, the
printing stops.
• Pressing the “Log Start” soft key initiates the print. After printing for the set record length,
the printing stops.
