Fluke 6070A - Frequency Modulation

Table 1-3. 6070A/6071A Specifications (cont)
Residual AM <0.02% rms in a 50 Hz to 15 kHz post detection
bandwidth on all bands.
AMPLITUDE MODULATION
Depth.0 to 99.9% In 0.1% steps where the total output level
(amplitude combined with AM) does not exceed 4-19
dBm peak at RF output frequencies below 520 MHz
or exceed +13 dBm peak for RF output frequencies
above 520 MHz.
Accuracy .±5% of full scale above 5 MHz or +5% to -8% of full
scale below 5 MHz for rates shown in the Distortion
specifications that follow. Amplitude accuracy is not
specified below -131 dBm.
