Microwave System Analyzer
The Anritsu ME538C measures the characteristics of the IF and baseband of terrestrial radio relay links or satellite links.
Characteristics Measured
- Group delay characteristics
- Linearity of modulator and demodulator
- Differential phase characteristics
- Differential gain characteristics
- IF amplitude characteristics
- BB amplitude characteristics (option)
- IF return loss (Optional return loss bridges are necessary)
- BB return loss (Optional return loss bridges are necessary)
- Sensitivity of modulator and demodulator
- Frequency deviation
- AM to PM conversion coefficient
- DC characteristic
- Power, gain and loss
