DAC SETUP
Sub-Menu
This sub-menu contains four items that control the Digital-to-Analog Converter
(DAC) Output of the Input Channel.
The DAC Output is only available if the instrument was purchased with Option 58i.
DAC. CHANNEL
Menu Item
This chooses which channel will drive the DAC Output. Normally, the DAC Output
is driven by the Input Channel (Channel 01), but that need not be the case. For
example, a Mathematics Virtual channel installed as Channel 02 could drive the
Input Channel’s DAC Output.
DAC. SOURCE
Menu Item
This designates the data source of the channel monitored by the DAC Output.
The options for this menu item are:
• “
TRACK
” means the live tracking value of the channel.
• “
PEAK
” means the highest value of the channel since the peak/valley detector
was last cleared.
• “
VALLEY
” means the lowest value of the channel since the peak/valley detector
was last cleared.
DAC. ZERO-SCALE
Menu Item
This specifies what value, in engineering units, corresponds to zero output on the
DAC Output.
“Zero output” might be 0 Volts, 2.5 Volts or 5 Volts depending on how the DAC
Output is configured. See “Digital-to-Analog (DAC) Output Configuration” on
page 114 for details.
DAC. FULL-SCALE
Menu Item Specifies what value, in engineering units, corresponds to full output on the DAC
Output.
“Full output” might be 5 Volts or 10 Volts depending on how the DAC Output is
configured. See “Digital-to-Analog (DAC) Output Configuration” on page 114 for
details.
