3.16 Tracking Generator (For DSA1030-TG)
The frequency response of a filter can be measured by using the tracking generator of
the analyzer. In the example below, we use a Low Pass Filter of 300 MHz as the filter
under measure.
Procedures:
1. Device attachment
Connect the filter under measure to the RF INPUT 50Ω and GEN OUTPUT 50Ω
terminal of the analyzer.
2. Measure the frequency response of a filter
(1) Reset the analyzer
－Press Preset
(2) Set the parameters
－Press FREQ
－Press Stop Freq and enter 1GHz.
－Press Source
－Press TG and select “On”.
(3) Normalization
Connect the RF INPUT 50Ω terminal to the GEN OUTPUT 50Ω terminal.
－Press Normalize and enter the lower menu.
－Press Stor Ref
Save the reference curve and eliminate the influence of the frequency
response from the analyzer itself.
Connect the filter under measure to the RF INPUT 50Ω and GEN
OUTPUT 50Ω terminal of the analyzer.
－Press Normalize and turn on the normalization.
3. Measurement result
The frequency response of the filter under measure is shown in the figure below.
