RF OUTPUT
The RF output is controlled by an ALC system in normal operation. When IQ modulation
is enabled, alternative control modes are available to optimize the performance of the
signal generator.
Range: Electronic attenuator
≤ 10 MHz −140 to +13 dBm
≤ 2 GHz −140 to +16 dBm
≤ 3 GHz −140 to +16 dBm
≤ 3.75 GHz −140 to +13 dBm
≤ 4 GHz −140 to +10 dBm
≤ 6 GHz −140 to +8 dBm
Mechanical attenuator
≤ 10 MHz −140 to +16 dBm
≤ 2 GHz −140 to +19 dBm
≤ 3 GHz −140 to +16 dBm
No attenuator
≤ 10 MHz 0 to +21 dBm
≤ 3 GHz 0 to +22 dBm
≤ 3.75 GHz 0 to +20 dBm
≤ 4 GHz 0 to +17 dBm
≤ 6 GHz 0 to +18 dBm
When AM is selected the maximum RF output level reduces linearly by up to 6 dB,
depending on the requested AM depth.
When IQ modulation is selected, maximum output is reduced by 6 dB below 100 MHz.
Resolution: 0.01 dB
RF level units
Units can be set to µV, mV, V EMF or PD; dB relative to 1 µV, 1 mV, 1 V EMF or PD; or
dBm. Conversion between dB and linear units may be achieved by pressing the
appropriate units key (dB or V, mV, µV).
