Analog Output Characteristics

The AL-1032 supports a variety of ways to configure a system that can output an analog voltage to a device under test. The following sections outline what sources are available, what enable triggers are compatible with each source, and whether the given channel requires an amplifier addon to support analog output.

	Supported	Trigger Types	Amplifier Addon [2]
Module AO Value
Ch 1..16	Yes	Internal, External	Not Supported
Ch 17..24	Yes	Internal, External	Not Supported
Ch 25..32	Yes	Internal, External	Required
Module AO (HI/LO)
Ch 1..16	Yes	External	Not Supported
Ch 17..24	Yes	External	Not Supported
Ch 25..32	Yes	External	Required
External AO
Ch 1..16	No	N/A	N/A
Ch 17..24	Yes [1]	None	Not Supported
Ch 25..32	Yes	Internal	Required

Warning

Enabling two output sources simultaneously may result in damage to the module.

[1]

The external connection is shared with the connection for other external hardware types. Only one external device per channel is supported.

[2]

If amplifier addon is required, no analog output is available without installing an Amplifer module in the corresponding bank. See Accessories for more information.

Module AO Characteristics

Given a desired analog voltage, the AL-1032 outputs the given voltage when the analog output is enabled.

Internal Enable, No Amplifier

Given an analog voltage, when the internal enable is active then the desired analog voltage is output on the corresponding DUT channel.
