Immunity Testing
Radiated Immunity When tested at 3 V/m according to IEC
801-3/1984, the displayed average noise
level will be within specifications over the
full immunity test frequency range of 27
to 500 MHz, except that at immunity test
frequencies of 278.6 MHz ± selected
resolution bandwidth and 321.4 MHz ±
selected resolution bandwidth, the
displayed average noise level may be up to
−90 dBm. When the analyzer tuned
frequency is identical to the immunity
test signal frequency there may be signals
of up to −90 dBm displayed on the screen.
Electrostatic Discharge In accordance with IEC 801-2/1991, an air
discharge of up to 8 kV, or a contact
discharge of up to 4 kV, will not cause any
change of instrument state or
measurement data. However, discharges
to center pins of front or rear panel
connectors may cause damage to the
associated circuitry.
