Auxiliary Tab

The Auxiliary tab provides access to the settings of the Auxiliary Inputs and Auxiliary Outputs; it is available on all UHF Series instruments.

Features

Monitor signal levels of auxiliary input connectors
Monitor signal levels of auxiliary output connectors
Auxiliary output signal sources: Demodulators, PIDs, Boxcars, AUs, AWG and manual setting
Define Offsets and Scaling for auxiliary output values
Control auxiliary output range limitations

Description

The Auxiliary tab serves mainly to monitor and control the auxiliary inputs and 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.

Control/Tool	Option/Range	Description
Aux		Controls all settings regarding the auxiliary inputs and auxiliary outputs.

The Auxiliary tab (see Figure 1) is divided into three sections. The Aux Input section gives two graphical and two numerical monitors for the signal amplitude applied to the auxiliary inputs on the back panel. In the middle of the tab the Aux Output section allows to associate any of the measured signals to one of the 4 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. The analog output voltages can be limited to a certain range in order to avoid damaging the parts connected to the outputs.

Please note the change of units of the scaling factor depending on what measurement signal is chosen.

Two Aux Output Levels on the right provides 4 graphical and 4 numerical indicators to monitor the voltages currently set on the auxiliary outputs.

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
Lower Limit	-10 V to 10 V	Lower limit for the signal at the Auxiliary Output. A smaller value will be clipped.
Upper Limit	-10 V to 10 V	Upper limit for the signal at the Auxiliary Output. A larger value will be clipped.
Value	-10 V to 10 V	Voltage present on the Auxiliary Output port. The value is obtained by clamping the calculated signal (Signal+Preoffset)*Scale + Offset based on Lower and Upper Limits.
Auxiliary Input Voltage	-10 V to 10 V	Voltage measured at the Auxiliary Input.
Signal		Select the signal source to be represented on the Auxiliary Output.
	PID Out	Select one of the PID controllers output. UHF-PID option needs to be installed.
	PID Shift	Select one of the PID controllers' shift signal. UHF-PID option needs to be installed.
	PID Error	Select one of the PID controllers' error signal. UHF-PID option needs to be installed.

	AU Polar	Select one of the two Arithmetic Polar units for auxiliary output.
	AWG	Select one of the AWG Outputs for auxiliary output when running the AWG in four-channel mode. UHF-AWG option needs to be installed.
	CNT Out	Select one of the Pulse Counter signals for auxiliary output. UHF-CNT option needs to be installed.
	X	Select the demodulator X component for auxiliary output.
