Features & Application
USG series offer several operating mode include fixed frequency, frequency sweep, frequency hopping and power sweep mode
Fixed Frequency mode:
- Be the reference source of PLL & ADC
- Be the local oscillator for frequency conversion device & IQ modulator
- Combine with external power amplifier can the RF interference source
- Combine with external attenuator can test the receiver sensitivity
- Two or more can be combined for Inter-modulation testing
Frequency sweep mode:
- Be the tracking generator source for scalar network measurement
- Test device frequency response
Frequency hopping mode:
- Test the receiver response time
Power sweep mode:
- Test the low noise amplifier

- Be the reference source of PLL & ADC
- Be the local oscillator for frequency conversion device & IQ modulator

- Combine with external power amplifier can be the RF interference source

- Combine with external attenuator can test the receiver sensitivity

- Two or more can be combined for Inter-modulation testing
