Boost the sensitivity of the 8566B spectrum analyzer with the 8449B

microwave preamplifier. This low noise, high gain preamplifier has a

frequency range of 1 to 26.5 GHz. Sensitivity improvements of up to 25 dB

allow you to detect and analyze very low level signals in dramatically

reduced time, using wider handwidths. Low return loss on the input and

output ports of the preamplifier minimizes mismatch uncertainty.

Displayed average noise level

0 dB attenuation, 10 Hz RBW (characteristic)

1.0 to 2.5 GHz -155 dBm

2.0 to 5.8 GHz -154 dBm

5.8 to 12.5 GHz -150 dBm

12.5 to 18.6 GH -144 dBm

18.6 to 22 GHz -140 dBm

The 8566B spectrum analyzer works with computers that support BASIC.

Center frequency readout accuracy

Spans ≤ n x 5 MHz ± (2% of frequency span + frequency reference error x

center frequency +10 Hz)

Spans > n x 5 MHz ± (2% of frequency span + n x 100 kHz + frequency

reference error x center frequency) where n is the

harmonic mixing number, depending on center frequency:

n center frequency

1 100 Hz to 5.8 GHz

2 5.8 to 12.5 GHz

3 12.5 to 18.6 GHz

4 > 18.6 GHz

(After adjusting freq zero, add 30% of RES BW setting if error correction is not used.)
