Check Level Measurement Uncertainty
This test checks the level measurement uncertainty at three reference levels: +10 dBm, 0 dBm, and –15 dBm. This check
uses the generator to step frequencies across four spans to verify that the instrument meets the specification.
For this check, you will need the following equipment, which is described in the Required Equipment table. (See Table 18
on page 33.)
Generator, such as the Anritsu generator
Power meter
Power head
Power splitter
Adapters and cables as shown in the following figure.
WARNING. The generator is capable of providing dangerous voltages. Be sure to set the generator to off or 0 volts before
connecting, disconnecting, and/or moving the test hookup during the performance of this procedure.
NOTE. Use an SMA connector with the Anritsu generator. Equipment damage will result if an N connector is used.
1. Connect the equipment as shown in the following figure.
2. Initial oscilloscope setup:
a. Push the Default Setup button on the front panel.
b. Push the front-panel RF button to turn on the RF channel.
