Trigger system
Trigger out functionality
A pulse is generated for every acquisition trigger
event.
output voltage
0 V to 5 V (nom.) at high impedance;
0 V to 2.5 V (nom.) at 50 Ω
pulse width selectable between 16 ns and 50 ms
pulse polarity low active or high active
output delay depends on trigger settings
Spectrum analysis
General description Spectrum analysis allows signal analysis in the frequency domain.
Spectrum sources channel 1, channel 2, channel 3, channel 4
setup parameters
center frequency, frequency span, automatic
RBW, resolution bandwidth, gate position, gate
width, vertical scale, vertical position
scaling dBm, dBV, dBµV, V (RMS)
span 1 Hz to 1.8 GHz
resolution bandwidth span/10 ≥ RBW ≥ span/8000
windows
flat top, Hanning, Hamming, Blackman,
rectangular, Kaiser Bessel, Gaussian
trace types normal, max. hold, min. hold, average
max. real-time waveform acquisition rate
> 40 000 waveforms/s
Gate delimits the display region used for spectrum analysis

RF characteristics
Sensitivity/noise density
at 1 GHz
(measurement of the power spectral density at
1GHz at input sensitivity 2 mV/div, corresponding
to –30 dBm input range of the oscilloscope, using
spectrum analysis with center frequency

Noise figure
at 1 GHz
(calculated based on the noise density above)
14 dB (meas.)
Dynamic range
measured for an input carrier with a frequency of
1 GHz and a level of –3 dBm at the input of the
oscilloscope, using spectrum analysis with center
