- Provide I/Q modulation and I/Q baseband output
- All the modulation functions support both internal and external modulation modes
- It is designed with a height of 2U which saves the rack space; it also provides the rack mount kit
- Provide USB/LAN remote control interfaces (standard) and standard SCPIcommand set
- Provide the system flatness calibration (cable, attenuator, amplifier and etc.) function
Support Multiple Modulation Methods
Standard amplitude modulation, frequency modulation, equal modulation analog modulation and pulse modulation and pulse generator, optional user-defined pulse sequence, and I / Q modulation and IQ baseband generator can generate QAM, ASK, PSK, FSK, Various commonly used modulation signals such as MSK; all modulations support internal and external modulation sources
Powerful Pulse Modulation
It produces high quality pulse modulated signals with rise/fall times typically less than 10 ns and on/off ratios greater than 70 dB. Support for internal and external modulation. Built-in pulse generator can generate pulse sequence and output to the outside as a separate pulse generator
Excellent Phase Noise
High signal purity, phase noise typical value <-112dBc/Hz@20kHz, similar products in the United States; better high-stability clock reference can get better near-phase noise index
Wide Range of High Power Output
Maximum output amplitude is +13dBm (nominal value), and can be set to +20dBm to meet the nonlinearity test of the amplifier.
Amplitude Stability
0.02dBExcellent repeatability provides engineers with sufficient test confidence that the 72-hour output amplitude variation is less than 0.02dB
