1. N is a factor used to help define certain
specifications. Refer to page 4 for N
value.
2. Specification valid for temperature chang-
es of less than ± 5 °C since last DCFM
calibration.
3. Typical performance immediately after a
DCFM calibration.
4. AM is specified at carrier frequencies
from 1 MHz to 3 GHz, power levels ≤
±4 dBm, and with ALC on and envelope
peaks within ALC operating range (–20
dBm to maximum specified power,
excluding step-attenuator setting).
