Auxiliary Tab¶

The Auxiliary tab provides access to the settings of the Auxiliary Outputs; it is available on all GHFLI instruments.

Features¶

Auxiliary output signal sources: Demodulators and manual setting
Define Offsets, Pre-offsets and Scaling for auxiliary output values
Control over the 4 High-speed and 4 High-precision auxiliary outputs

Description¶

The Auxiliary tab serves mainly to control the auxiliary outputs. Whenever the tab is closed or an additional one of the same type is needed, clicking the following icon will open a new instance of the tab.

The Auxiliary tab (see Figure 1) allows to associate any of the measured signals to one of the 8 auxiliary outputs on the instrument front panel. With the action buttons next to the Preoffset and Offset values the effective voltage on the auxiliary outputs can be automatically set to zero (this functionality will be available soon).

Functional Elements¶

Table 2: Auxiliary tab
Control/Tool	Option/Range	Description
Preoffset	numerical value in signal units	Add a pre-offset to the signal before scaling is applied. Auxiliary Output Value = (Signal+Preoffset)*Scale + Offset
Auto-zero		Automatically adjusts the Pre-offset to set the Auxiliary Output Value to zero.
Scale	numerical value	Multiplication factor to scale the signal. Auxiliary Output Value = (Signal+Preoffset)*Scale + Offset
Offset	numerical value in Volts	Add the specified offset voltage to the signal after scaling. Auxiliary Output Value = (Signal+Preoffset)*Scale + Offset
Signal		Select the signal source to be represented on the Auxiliary Output.
	X	Select the demodulator X component for auxiliary output.
	Y	Select the demodulator Y component for auxiliary output.
	Manual	Manually define an auxiliary output voltage using the offset field.
Channel	index	Select the channel according to the selected signal source.
