1 General Information

IF (OUTPUT)

The signal at this connector is the downconverter’s output.

Limits

• Nominal output level: 0 to +5 dBm (input signal ≥ –30 dBm)

• Maximum output level: +15 dBm

• Frequency (RF input 5 to 1500 MHz): 5 to 1500 MHz

• Frequency (RF input 5 to 26.5 GHz): 300 to 900 MHz

Characteristics

• Output impedance: 50 Ω

RF SIGNAL (INPUT)

This connector accepts a 120 MHz signal from a synthesized signal generator.

This signal is mixed with the internal microwave local oscillator. The result is a

tunable microwave signal with a 0.1 Hz resolution over most of the frequency

range.

Limits

• Maximum input level: +10 dBm

• Recommended input level: –10 to +5 dBm

• Frequency: 120 to 900 MHz

Characteristics

• Input impedance: 50 Ω

NOTE

The IF amplifiers frequency response starts rolling off above 1200 MHz. Avoid using IF

frequency between 1200 and 1500 MHz.
