Making Mixer Measurements
High Dynamic Range Swept RF/IF Conversion Loss
NOTE Because power meter calibration requires a longer sweep time, you may want to reduce the
number of points before pressing
. After the power meter
calibration is finished, return the number of points to its original value and the analyzer will
automatically interpolate this calibration.
Perform a Receiver Calibration Over the IF Range
1. Connect the measurement equipment as shown in Figure 2-17.
Figure 2-17 Connections for Receiver Calibration
2. To calibrate the B-channel over the IF range, press:
Once completed, the analyzer should display 5 dBm.
Set the Analyzer to the RF Frequency Range
You can find the RF frequency range by using a simple calculation or using the mixer measurement diagram
on the analyzer display.
Using the Calculation
Add the LO frequency to the IF frequency start and stop values. If using an LO frequency of 1500 MHz, the RF
start frequency would be 1.6 GHz (1500 + 100 MHz) and the stop frequency would be 2.5 GHz (1500 + 1000
MHz).
