Characteristics Description
Amplitude Range For a CW signal at speci fi ed frequencies in each path.
Each path is calibrated at a single frequency (see Amplitude Accuracy). For signals at different
frequencies, the range is shifted and the actual output power will be offset from the requested
power. The speci
fi cations for the no fi lter path at 13 GHz and the band pass path at 18 GHz
re fl ect the capability at those frequencies, not the accuracy.
No fi lter 25 dBm to –70 dBm at 1 GHz
18 dBm to –77 dBm at 13 GHz
Low Pass
25 dBm to –70 dBm at 1 GHz
Band Pass
10 GHz to 14.5 GHz 18 dBm to –77 dBm at 11 GHz
13 GHz to 18 GHz 20 dBm to –90 dBm at 14 GHz
18 dBm to –90 dBm at 18 GHz
Amplitude resolution 0.01 dB
Amplitude accuracy The AWG does not include a leveling loop. Signal amplitude accuracy is only speci fi ed for a
CW signal at the calibration frequency. Signals at different frequencies can have a different
amplitude. Modulated or multi-tone signals often have signi
fi cantly lower amplitude.
Calibration is done with a small signal to keep the ampli fi er in a linear range. When playing
out full amplitude signals at high levels the ampli fi ers can be driven into compression and the
output amplitude will not match the requested level and the signal can be distorted.
