Connecting an RF Signal
The spectrum analyzer has a single RF signal input located on the front panel. The input impedance is
50
Ω . The input frequency range is 9 kHz to 6.2 GHz (RSA6106A), 9 kHz to 14 GHz (RSA6114A). The
maximum measurable continuous input power is 1 W.
To connect an RF signal:
1. If the source signal is greater than 1 Watt (+30 dBm), connect the source signal to an attenuator.
Connect the attenuator output to the RF Input connector.
CAUTION.
To prevent damage to the spectrum analyzer, do not connect signals greater than +30 dBm
(1 Watt).
CAUTION.
To prevent damage to the spectrum analyzer, do not turn the equipment under test on or off
with a LISN (Line Impedance Stabilization Network) RF cable connected to the spectrum analyzer. The
power cycling of the equipment under test causes surge currents that can damage the sensitive input of
the spectrum analyzer.
2. Connect the signal to the RF INPUT connector.
The maximum limits for the input signal are as follows:
Characteristic
Description
Maximum DC Voltage ± 40 V (RF input)
+ 30 dBm (RF input, RF ATT Auto)
Maximum Measurable Input Power
75 Watts peak (RF Band, RF ATT Auto (<10 ms pulse width,
1% Duty Cycle repetitive pulses)
