Invert function Polarity reversal
Vernier function Included
Commenting Alphanumeric and Japanese characters (title for each analog and logic channel)
Comment entry
method
Simple input by using the keys of the Memory HiCorder, mouse, and keyboard
Stored string and historical string entry (pre-stored and previously used strings can be
recalled, inserted and edited)

settings
Copy and paste, or paste all
Logic setting
Width: Selectable from three types: wide, standard, and narrow
Display position: Freely settable in increments of 1%
Display bits: Off or selectable from among 16 colors, settable individually for each bit
Zoom function The waveform screen is divided vertically in two, and the lower portion displays zoomed
waveforms.
Trigger Function
Trigger method Digital comparison
Trigger modes •Memory function, FFT function: Single, Repeat, Automatic
•Recorder function: Single, Repeat
Trigger source Analog Unit (CH1 to CH32), Standard Logic 32 Channels
Independent trigger criteria settable for each channel
Free-run operation occurs when all trigger types are off.
External Trigger occurs by applying a 2.5 V falling edge signal, shorted terminals
Manual trigger, Timer trigger
Trigger criteria AND or OR of each trigger source
