GENERAL DESCRIPTION

The 3002 is a synthesized VXI signal generator covering the frequency range 9 kHz to

 

2.4 GHz.

 

 

 

 

The RF output can be amplitude, frequency, phase or pulse modulated. An internal

 

programmable AF source is capable of generating simultaneous two-tone modulation.

 

All functions can be controlled by an IEEE 488.2 message-based interface.

Range

-137 dBm to +25 dBm (+19 dBm above 1.2 GHz).

 

 

 

When AM is selected, the maximum RF output level decreases linearly with increasing

 

AM depths to +19 dBm (+13 dBm above 1.2 GHz) at 99% depth.

Resolution

0.1 dB

 

 

 

Accuracy

 

 

 

 

 

Attenuator hold

Selection of attenuator hold provides for uncalibrated level reduction of at least 10 dB

 

without the mechanical attenuator operating.

 

 

GENERAL INFORMATION

VSWR

Output impedance

Output protection

SPECTRAL PURITY

For output levels less than -5 dBm output VSWR is less than 1.3:1 for carrier frequencies up to 1.2 GHz and less than 1.5:1 for carrier frequencies up to 2.4 GHz.

50 SMA female connector to MIL 390123D.

Protected from a source of reverse power up to 50 W from 50 or 25 W from a source VSWR of 5:1. Tripping of the reverse power protection circuit illuminates a front panel LED and raises an interrupt. The protection circuit can be reset remotely.

Harmonics

Typically better than -30 dBc for levels up to +7 dBm,

 

typically better than -25 dBc for levels 6 dB below the maximum specified output.

Non-harmonics (offsets >

Better than -70 dBc for carrier frequencies up to 1 GHz,

3 kHz)

better than -64 dBc for carrier frequencies above 1 GHz,

 

better than -60 dBc for carrier frequencies above 2 GHz.

Residual FM (FM off)

Less than 4.5 Hz RMS in a 300 Hz to 3.4 kHz bandwidth at a carrier frequency of

 

1 GHz.

SSB phase noise

Better than -124 dBc/Hz at 20 kHz offset from a 470 MHz carrier.

 

Typically -121 dBc/Hz at 20 kHz offset from a 1 GHz carrier.

ΦM on AM

Typically 0.1 radians at 30% depth at 470 MHz.

MODULATION

Internal and external modulation can be simultaneously enabled to produce combined

 

amplitude and frequency (or phase) modulation. Pulse modulation can be used in

 

combination with the other forms of modulation.
