Microsecond fast frequency hopping ability

Frequency bandwidth is up to 60MHz, and frequency hopping rate is up to over 2000h/s, which can meet most frequency agility applications.

Wide dynamic range of power and high power accuracy
Dynamic range of output power is up to more than 120dB with high power accuracy so as to flexibly analog signal transmission in space and amplitude strength.

Multiple sweep modes: digital step, frequency hopping, phase continuation
Digital step sweep has main advantages of wide range of sweep frequency, frequency synthesis, checking the characteristics of wideband radio frequency device quickly and finishing the detection of wideband RF devices such as wideband filter, RF amplifier, mixer etc. quickly. Without discrete frequency step, phase continuous sweep can measure devices with high Q more quickly than digital step sweep and fast frequency hopping sweep, which guarantee not to lose some key peaks and depressions, therefore, it is especially suitable for the precise test for narrowband devices’ features.

Frequency modulation/Amplitude modulation/Phase modulation/Pulse modulation and Compound modulation
It offers multiple compound simultaneous modulations.
Amplitude modulation: frequency modulation, phase modulation; Frequency modulation: amplitude modulation, pulse modulation;
Phase modulation: amplitude modulation, pulse modulation; Pulse modulation: frequency modulation, phase modulation.

Digital baseband signal generation and vector modulation
Digital baseband signal generation and vector modulation offer multiple digital modulation modes including BPSK, QPSK, 2FSK, 4FSK and MSK. Communications signals that user requires can be generated by changing modulation mode, RB, filter form and filter coefficient etc., which is used for testing of receiver.

Multi radar signal analog ability
It can generate frequency agile signal, chirp signal, pulse PRF jittering, PRF staggering signal and antenna sweep analog signal etc., as well as can analog continuous wave radar, frequency agile radar, pulse compression radar, pulse PRF jittering radar, pulse PRF staggering radar and pulse Doppler radar.

Data transmission, communication and printing functions
With multiple communication modes such as network interface, USB interface and GPIB interface etc., waveform files can be operated by remote control through the network interface and USB interface.

USB interface
With fast USB interface that is plug and play and can realize storage and recall of files quickly or software upgrading of instrument, the instrument supports U disk and MP3.with protocol 1.0

Network interface
With the network interface, the instrument software can be upgraded quickly. Computer can be connected directly or through Huber with more than two holes with the instrument for remote control.  

GPIB interface
With GPIB interface, computer can realize remote control to the instruments, as well as compose test system with other instruments so as to realize automation of testing.
