Table 1-2. HP 3048A System Option Specifications (4 of 9)

OPTIONS 003 OR 004: ADDING THE HP 11729C

OR 11729C OPT 130 CARRIER NOISE TEST SET

The following data is applicable to using the HP 11729C to

downconvert the test signal to an IF of between 5 MHz and

1280 MHz for subsequent demodulation using the Low

Frequency phase detector of the HP 3048A system, The

HP 8662A Opt. 003 or 8663A Opt. 003 Signal Generators

provide a 640 MHz reference signal for this downcoversion

process. These signal generators also provide a signal of

between 5 MHz to 1280 MHz to demodulate the

downconverted IF noise. The specifications that follow assume

this measurement set-up is used.

Input Requirements

Frequency

Measurement Frequency Range: 5 MHz to 18 GHz in 8

bands,

excluding ±5 MHz around band center frequencies.

Band Center Frequencies: 1.92 GHz, 4.48 GHz, 7.04 GHz,

9.60 GHz, 12.16 GHz, 14.72 GHz, 17.28 GHz.

Amplitude

For carrier frequencies <1.28 GHz: -5 dBm minimum to

+23 dBm maximum.

For carrier frequencies >1.28 GHz: +7 dBm minimum to

+20 dBm maximum.

Measurement Specifications

Offset Frequency Range

For carriers between 5 and 95 MHz from band centers:

0.01 Hz to 2 MHz.

For carriers >95 MHz from band center: 0.01 Hz to

40 MHz.

(Assumes addition of 40 MHz spectrum analyzer to the

system, otherwise offset frequency range limited to

100 kHz.)

System Noise Floor

Absolute System Noise Floor (dBc/Hz), when used with the

HP 11729C and HP 8662A Option 003 or HP 8663A Option

003 as the reference source, phase locking via the signal

generator's EFC.

Specified only with FM off.
