CS Bound -- Pre-Test Calibration Level

The Pre-Test Calibration Level option establishes the upper bound by calculating power, voltage, or current for a fixed impedance.  During CS analysis calculations the injected signal is limited to the values established by the upper bound.

This option is appropriate when the CS requirement states that the CS injection levels are not to exceed a power, voltage, or current threshold across or through fixed impedance.

For example, MIL-STD-461E states, "Requirements are also met if the EUT is not susceptible at forward power levels sensed by the coupler that are below those determined during calibration provided that the actual current induced in the cable under test is 6 dB or greater than the calibration limit."  For more information, refer to MIL-STD-461E.

Watts

If the Watts option is selected, enter the specified power level in the first text box and the specified load impedance in the second text box.

For example, if the upper bound is specified as, "1.00E+00 watts into a 5.00E+01 ohm load" the upper bound on CS injected voltage will be 7.07 Volts and the upper bound on current will be 141.4 mA.

Volts

If the Voltage option is selected, enter the specified voltage level in the first text box and the specified load impedance in the second text box.

If the CS Limit is specified in terms of voltage and the upper bound is specified as, "3.00E+00 volts into a 1.00E+02 ohm load" the upper bound on CS injected voltage will be 3.0 volts and the upper bound on current will be 30 mA.

Amps

If the Amps option is selected, enter the specified current level in the first text box and the specified load impedance in the second text box.

If the CS Limit is specified in terms of current and the upper bound is specified as, "5.00E+00 amps into a 2.00E+00 ohm load" the upper bound on CS injected voltage will be 5.0 amps and the upper bound on voltage will be 2.5 volts.
