Operation
Connecting a Signal
The analyzer has a single R F signal input located on the front panel. M ake sure that you observe the input signal
requirements before connecting a signal to the input.
CAUTION. To prevent static damage to the instrument or to any instrument accessories, discharge to ground any
electrostatic charge that may be present on the center and outer conductors of cables, before attaching the cables to the
instrument inputs. Do not create an ESD (electrical static damage) antenna by leaving cables attached to the instrument with
the other ends of the cables open.
Required Signal Levels
The following table shows the input signal levels over which the analyzer can be used for m easurements. The accuracy is
guaranteed at a signal amplitude and frequency (normalization point). Measurements c an be made on signals within the
entire ran
ge of allowable inputs, but the accuracy of the measurem ent is affected by the frequency and amplitude of the
signal to be measured (see the RSA6100A Series or RSA5100A Series data sheet for more information).

CAUTION. To prevent damage to the instrument, do not connect CW signals greater than 1 Watt (+30 dBm). For the
RSA6100A Series, the maximum voltage rating is ±40 V DC. The maximum pulse specifications are 75 W peak, 10 μs pulse
wi
dth, 0.001 duty cycle, and ≥30 dB attenuation. For the RSA5100A Series, the maximum voltage rating is ±5 V DC. The
maximum pulse specifications are 50 W peak, <10 µs pulse width, 0.001 duty cycle and ≥30 dB attenuation.
