IQ vector generation function, Sufficient modulation and sweep functions.


IQ modulation signal output

64QAM output

The IQ modulated signal is output by inputting such IQ signal as analog, digital or list data(USB memory and manual) in IQ modulator (option) from the outside.

Fast switching

The fast switching of 0.5μs at frequency (however, 1.5ms at 10N-3(MHz)(N: integer) point) and 200μs at level is possible. For command and external trigger receiving, both are 1.5ms (however, 3ms at frequency 10N-3(MHz)(N: integer) point).

ALC function

MSG703 ensures the high accurate RF output level by ALC circuit (Auto Level Control circuit).

High accurate frequency and level output

The frequency can be set at maximum 11 digits in 0.1Hz resolution. The accuracy of level is ± 0.6dB (excluding 625 to 725MHz) in “ALC on”.

Frequency and level setting by three ways

Since frequency and level can be set by using ten key, rotary encoder and arrow key, the operability will increase dramatically.

Abundant modulation functions

Spectrum waveform of FSK(PN15)

FSK and PSK of digital modulation, and AM of analog modulation are provided as standard. FSK and PSK have the register mode with fast transmission rate and the direct mode with generation of arbitrary modulation.
In addition, the burst control is available.

They can be used simultaneously with the sweep function. Frequency hopping is possible.

Sufficient sweep functions

Sweep waveform

MSG703 has the list sweep by arbitrary lists of frequency and level, and the step sweep at which frequency/level from the start until the stop is swept by specified step. Moreover, it is possible to control the sweep by the trigger signal, and there are four trigger modes of edge 1, edge 2, level 1 and level 2.

Phase offset function

The phase of the output signals of two MSG703 can be synchronized.

Small size and lightweight

Since MSG703 is portable size as 360 (W) × 160 (H) × 360 (D) mm and is lightweight as 8.5kg, it can be used easily anywhere and anytime.

Sufficient interfaces

USB host, USB device and LAN (1000BASE-T) are equipped as standard.

Large and color LCD display
