Using the Tracking Generator 1/4 Wave Coaxial Filter Tuning (Swept) This procedure is used to measure the notch depth and or band-pass of a 1/4 wave coaxial filter using the Spectrum Analyzer/Tracking Generator option. Pass frequency is measured, and can be adjusted by trimming length from the coaxial filter.

Connect the Tee as shown. CAUTION: Do not exceed the connector’s rated input or permanent instrument damage may result.
Page 218 Using the Tracking Generator NOTE: Amplitude default of 0 dBm is typically sufficient for performing measurements on 1/4 Wave Coaxial Filters. The level can be changed as required to suit measurement needs (e.g. increase measurement range, minimize incident input from other sources, etc.). If Amplitude is changed, Ref Level will also have to be changed.

Page 247 Preparing the Test Set for DC Operation CABLING When cabling the DC connector, remember that varying wire gauge, RESTRICTIONS type, and length will yield different resistive losses. Proper operation of the Test Set requires that a minimum of 11 Vdc at 12 Adc be present at the DC input connector.
Page 248 Preparing the Test Set for DC Operation Preparing the Test Set for Operation 1. Verify that the instrument is connected and configured to the appropriate power source. NOTE: Because most parameters are saved when power is removed, setting configuration is NOT necessary every time power is applied to the Test Set. Perform these procedures only if changes to the fields are required.
