DVM - Design Verification Module

DC Input Susceptibility Source

The DC input susceptibility source injects a small signal AC voltage into the input during an AC analysis. For the POP and transient analyses, the small signal portion of the source is disabled and the source is modeled by a constant DC voltage and a source resistance.

Unlike the DC Input Impedance Source, this source doesn't include any probes to generate the conducted susceptibility plots. Instead, the plots are created using a special conducted susceptibility probe.

DC Input Susceptibility Source Parameters

The following table explains the relevant parameters.

Parameter Name

Default

Data Type

Range

Units

Parameter Description

DC_VOLTAGE

5

Real

min:0

V

DC voltage of input source

SOURCE_NAME

SRC

String

n/a n/a

Name of the DVM source. This name cannot contain spaces.

SOURCE_RESISTANCE

0.4

Real

min:0

Sets the source resistance of the source.

MEASURE_SUSCEPTIBILITY

0

Real

0 or 1   A flag used by DVM to measure the Conducted Susceptibility for this input source. This flag also enables the small signal AC source. When both MEASURE_SUSCEPTIBILITY and MULTI_TONE are equal to 1, the source is set to measure a Multi-Tone Input Impedance.

MULTI_TONE

0

Real

0 or 1   Enables Multi-Tone AC analysis for this source. For small signal POP and AC analyses, this is set to 0.

DC Input Susceptibility Source - Multi-Tone AC Analysis

The following table summarizes the parameters used when a Multi-Tone AC Analysis is specified. The source uses these parameters only if the MULTI_TONE property is set to 1.

Parameter Name

Parameter Description

INJ_AMP

10m

Real

 

V

The RMS injection amplitude for the Multi-Tone AC source included in this source.

MEASURE_SUSCEPTIBILITY

0

Real

0 or 1   A flag used by DVM to measure the Conducted Susceptibility for this input source. This flag also enables the small signal AC source. When both MEASURE_SUSCEPTIBILITY and MULTI_TONE are equal to 1, the source is set to measure a Multi-Tone Input Impedance.

MULTI_TONE

0

Real

0 or 1   Enables Multi-Tone AC analysis for this source. For small signal POP and AC analyses, this is set to 0.

N_PT

10

Real

    The number of points per decade when the SWEEP_MODE is 1 or 2. Unused when the SWEEP_MODE is 0.

START_FREQ

1k

Real

  Hz The starting frequency for the Multi-Tone AC Analysis

STOP_FREQ

100k

Real

  Hz The ending frequency for the Multi-Tone AC Analysis

SWEEP_TYPE

1

Real

0, 1 or 2
 
  One of the following:
  • 0 = Linear Sweep
  • 1 = Decade Sweep
  • 2 = Decade sweep with linear first decade

TIME_DELAY

10u

Real

  s The time delay for the AC Multi-Tone injection. This time delay is converted into a phase delay and is used to ensure that the Multi-Tone AC injection starts at the same phase angle where the FindAcSteadyState() test ended.
