Input level to RF Input
Frequency range: 9 kHz to 7.8 GHz (MS8608A), 9 kHz to 13.2 GHz
(MS8609A)
Measurement level: Apply the measured signal with average noise level up
to +40 dBm (MS8608A) or +20 dBm (MS8609A) to
the N-type connector High Power (MS8608A) or RF
(MS8609A) Input of 50
Ω
input impedance,
respectively.
CAUTION
The RF Input (MS8609A) and High/Low Power Input
(MS8608A) circuits are not protected against excessive
power.
If a signal exc40 dBm (High Power Input of
MS8908A) or 20 dBm (RF Input of MS8609A and Low Power
Input of MS8608A) is applied, respectively; the power sen-
sor, input attenuator and input mixer may be burned.
is a warning mark to prevent such damage.
Caution of handling the RF Input Connector
Use the N-type connector for the RF Input of the MS8609A and High Power Input of
the MS8608A, and SMA-type connector for the Low Power Input of the MS8608A.
If different connector is connected, there is an accidental risk of damage to the RF input
connector.
