Description
DC to 1 GHz < 1.4:1.
1 GHz to 3 GHz < 1.6:1.
3 GHz to 4 GHz < 2.0:1.
10 MHz to 1 GHz < 1.6:1.
1 GHz to 4 GHz < 2.0:1.
10 MHz to 1 GHz < 1.4:1.
2 GHz to 4 GHz < 1.5:1.
In NRZ mode, each sample is held for the entire sample period (1/sample rate). This results
in the familiar sin(x)/x frequency response. With DDR mode enabled, the sin(x)/x bandwidth
doubles.
In RZ mode, each sample is held for half of the sample period. This doubles the sin(x)/x
bandwidth, but reduces the amplitude by half. This may be useful when playing a real
waveform with the signal in the second Nyquist zone. For real waveforms, DDR mode filters
the signal in the 2nd and 3rd Nyquist zones and is not useful in this case.
In Mix mode, each sample is inverted for the second half of the sample period. This is
effectively like mixing the output waveform with the sample clock. This boosts the signal in
the second Nyquist zone, but zeros the DC component of the waveform and reduces low
frequency components. This may be useful when playing a real waveform with the signal in
the second Nyquist zone. For real waveforms, DDR mode filters the signal in the 2nd and 3rd
Nyquist zones and is not useful in this case.
4.44 GHz * fsample ÷ 10 GS/s (DDR Mode).
fsample = sample rate.
The sin(x)/x bandwidth can be solved by using the following equation:
20 * log (sin(x)/x) = –3.
x = π * fout ÷ fsample.
fsample = sample rate.
fout = sin(x)/x bandwidth.
Independent amplitude control for all channels.
Units of dBm or V can be selected.
