HP 8662A input
This connector accepts a 120 MHz to 900 MHz signal from an HP 8662A or
HP 8663A. 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.
•
Maximum input level: +10 dBm
•
Recommended input level: –10 to +5 dBm
•
Frequency: 120 MHz to 900 MHz
•
Input impedance: 50 Ω
Setting frequency
The HP 70428A Option 002 is designed to work with an HP 8662A or HP
8663A signal generator. Normally an HP-IB cable is connected between the
MMS mainframe and the HP 8662A or HP 8663A. The HP 70428A Option
002 acts as a controller and tells the HP 8662A or HP 8663A what frequency
to set. In remote operation, the signal generator must be programmed
separately. If another signal generator is used you must determine and set its
frequency manually.
