Gx3722DigitizerGetTermination

Purpose

Returns the current state of the digitizer termination resistors.

Syntax

Gx3722DigitizerGetTermination (nHandle, pnLoad, pnStatus)

Parameters

Name
Type
Comments
nHandle
SHORT
Handle to a GX3722 board.
pnLoad
PSHORT
Returns the channels where the 75Ω termination resistor is applied:
0.      GX3722_DIGITIZER_TERMINATION_NONE: No termination resistors.
1.      GX3722_DIGITIZER_TERMINATION_CH1: 75Ω across channel 1 only.
2.      GX3722_DIGITIZER_TERMINATION_CH2: 75Ω across channel 2 only.
3.    GX3722_DIGITIZER_TERMINATION_BOTH: 75Ω across both channels.  
pnStatus
PSHORT
Returned status: 0 on success, negative number on failure.

Comments

The digitizer channels each have a 75Ω, 2-Watt resistor available to bridge the positive and negative input pins.  By default, this termination resistor is not connected.

Example

The following example gets the current termination resistor state:

 

SHORT nLoad;

Gx3722DigitizerGetFrequency (nHandle, &nLoad, &nStatus);
