IMPEDANCE MATCHING KEYSIGHT ADS HOW TO

Set the Reference Impedance to the value of.

Impedance-matching device (50W in this example).

Set the Input Impedance to the output value of the.

In this case, set the following parameters: The impedance-matchingĭevice must have an input impedance equal to the output impedance of theĭevice under test and an output impedance equal to the measurement hardware's input Of the device under test and the input impedance of the measurement do not Because the two impedances match, no external amplitude The DUT impedance and select Same as Input. Test has an output impedance that matches the measurement hardware input impedance, Insertion loss compensation value in the Gain

Click the Amplifier/Attenuator check box.

Matching device, attenuator, or measurement probe that has insertion loss is used,

Specify the Reference Impedance to match the DUT output characteristic.

Set the Input Impedance parameter to match the impedance of the impedance-matchingĭevice that is connected to the input of the measurement hardware.

When there is a DUT and measurement hardware input impedance mismatch.

The following steps show how to set up a measurement Parameter ( Input > User Correction > Amplifier/Attenuator). Also, any impedance matching device insertion loss can be compensated for Voltage and the Reference Impedance value to calculate the power in dBm. With the Input Impedance parameter to calculate dBm. The Reference Impedance parameter is used in conjunction When there is an impedance mismatch between the DUT and the input of the measurement hardware, the Same as Input checkbox is cleared. No changes are required to the Input Impedance or Reference Impedance parameters. and measurement hardware input impedance are the same, The MSC switches all calls between the mobile and the PSTN and other mobiles. The apparatus can range from a single component to a complex subsystem such as a mobile phone, base station or MSC Mobile Switching Center: The location providing the mobile switching function in a second generation network wireless network. When the DUT Device under Test: An acronym used to describe some type of electrical apparatus connected to test instrumentation. Click the arrow button to view the Reference Impedance selection for each available channel. If the selections for individual channels are different, the arrow button ( ) after the Reference Impedance text box will be orange. The available channels are displayed in Logical Channel located at the top of the dialog box.

This parameter can be selected for All channels or individually for each available channel. The Reference Impedance can be specified to match the Input Impedance by selecting Same as Input or set separately by clearing the Same as Input checkbox and entering an impedance in the text box. In the nominal input impedance of the analyzer for the selected Logical Channel. Uses to calculate the power in dBm deciBels referenced to a milliWatt: dB relative to 1 milliwatt dissipated The Reference Impedance parameter specifies the reference Reference Impedance Reference Impedance (Input Analog Tab)
