Analog Input Menu 4-79
SR780 Network Signal Analyzer
The two displays have their own Engineering Units mode. This entry
field can be linked to both displays using the [Link] key.
Command: EU1M (?) {i} or EU2M (?) {i}
EU Label
Choose the Engineering Units Label for the Ch1 or Ch2 input. The
displayed units change from Volts to the EU Label when Engineering
Units are On. Choose USER for the user defined User Label.
Input units of acceleration (m/s
2
or in/s
2
), velocity (m/s or in/s), and
displacement (m or in) may be converted within a frequency domain
display using Transducer Convert in the [Display Options] menu. For
example, the FFT of an input configured for an accelerometer with
Engineering Units of m/s
2
may be displayed in displacement (meters)
using Transducer Convert.
The two displays have their own EU Label. This entry field can be linked
to both displays using the [Link] key.
Command: EU1L (?) {i} or EU2L (?) {i}
EU / Volt
Set the Engineering Units per Volt scale factor for the Ch1 or Ch2 input.
This factor is used to scale the display units from Volts to Engineering
Units when Engineering Units are On. The displayed units change from
Volts to the EU Label.
The EU scale factor may be entered in EU/V, V/EU, or dB(EU/V). In all
cases, the EU scale factor is displayed in EU/V along the vertical axis
whenever a measurement takes its input from an input with Engineering
Units On.
The two displays have their own EU scale factor. This entry field can be
linked to both displays using the [Link] key.
Command: EU1V (?) {x} or EU2V (?) {x}
EUs at Marker
Calculate the EU/Volt scale factor for either the Ch1 or Ch2 input based
upon the marker reading in the active display. Enter the desired
calibrated value for the marker reading (in the display units).
