1.3 Display
18
This instrument allows you to use a commercially available LCD monitor for displaying waveforms
and various settings.
1.3 Display
• The instrument’s DVI connectors are designed exclusively for digital. They
cannot be used for analog.
A VGA-DVI adapter also cannot be used.
• There are a variety of LCD monitors available, and not all LCD monitors will
work with the instrument.
• The display aspect ratio for DVI output with this instrument is 4:3. If you use a
wide LCD (16:9), display will be stretched in the horizontal direction.
• External interference may cause display to be distorted. Keep the LCD and
LCD cable as far away as possible from sources of interference.
• MR8740 displays the waveforms of the block I side (32 analog channels + 8
logic channels) with DVI-I, and the waveforms of the block II side (22 analog
channels + 8 logic channels) with DVI-II. The waveforms of block I and block II
cannot be displayed at the same time.
Connect the LCD monitor to a DVI-D connector on the front of the instrument.
