Summary
Page 2 - Introduction; capable of setting
2 Introduction Designers and manufacturers of active devicesoften need to control the power level at the testport 1 of their power-sensitive devices, but find dif- ficulty in overcoming insertion losses. The insertionlosses occur as a result of connecting componentsin the measurement path between th...

3 System Configuration The basic 8510C measurement system configura-tion needed for test port f latness correction isshown in Figure 1. A single channel power metersuch as the Agilent 437B, E4418A, or E4418B isrequired, along with a compatible sensor, for per-forming the power f latness calibration....

4 Flatness-Correction Operation The basic setup procedure to obtain f lat test portoutput power is illustrated in Table 1. To simplifythe execution of the procedure, the front panelhardkeys are enclosed in [brackets]. The softkeysare enclosed in {braces}. Table 2 provides the pro-cedure for setting ...
5 Table 1. Flatness-correction calibration procedure 8510C Keystrokes Description Set up the power meter (see Table 2) For proper operation, the E4418B must be set up before initiating the flatness-correction routine. See Table 2 for specific instructions. Verify the power meter's address on the 851...

7 The following error messages may occur whileattempting to enable the f latness correction and/orreducing the test port power level: • If f latness correction is enabled before reducing the test port power level, IF Overload or Source 1 Warning—RF Unleveled may be displayed on the analyzer as the s...
Page 9 - Using test port 1 calibrations on test port 2
9 Using test port 1 calibrations on test port 2 In most cases, port 1 will be the input port of theDUT. When port 2 must be used as the input portto the device, the user may choose to use a port 1f latness-correction calibration on port 2 since theport 1 and port 2 signal paths are symmetrical. 1 Fi...
Page 10 - Practical Application Examples
10 Practical Application Examples Absolute output power measurements with flatness correction One benefit of the f latness-correction capability isthe ability to measure the absolute output power ofactive devices. Since the input power level to theDUT is kept constant, the magnitude offset featureof...

11 Amplifier measurement example Step-by-step instructions for setting up and apply-ing f latness corrections for the measurement of an amplifier are shown in Table 7. Gain, absolute output power, and gain compression measurementsprocedures are covered. For more information onmeasuring amplifiers, r...
