Zero Span Audio Demodulation
Internal loudspeaker with adjustable volume and mute
30 mW into 32 Ohms mono or stereo headphones, adjustable volume,
3.5mm jack socket (auto disconnect of internal loudspeaker)
Selectable low-pass filter to attenuate high frequency interference.
2 pole filter with turnover point at approximately 3 kHz.
Zero Span Waveform Demodulation (only with Option U02)
AM Waveform, FM Waveform, Carrier Level or Carrier Waveform.
+/-5% to +/-100% full scale (AM) or +/-1kHz to +/-1MHz full scale (FM).
Variable trigger point on rising or falling edge.
13.1.2 Amplitude Measurement (Level)
Amplitude Range
dBm or dBµV (dB milliwatts or dB micro volts)
Selectable between -40dBm (67 dBµV) and +20dBm (127 dBµV) with a
resolution of 1dB
Amplitude Accuracy
Better than ± 1 dB at 2000 MHz at 10 dB below reference level
Better than ± 1 dB relative to 2000 MHz over 10 MHz to 6000 MHz
[10 MHz to 3600 MHz]
Better than ± 1 dB over 60dB range down from reference level
Displayed Average Noise Level (DANL)
Better than – 120 dBm (-13 dBuV) average displayed noise floor
(ref. level = – 40 dBm (+67 dBuV), RBW = 10 kHz, VBW = 1 kHz, span
1MHz) over 10 MHz to 5500 MHz [10 MHz to 3600 MHz]
Better than -160 dBm per Hz equivalent
Distortion and Spurii
< – 60dBc (typically -65dBc) for two signals at 10dB below the
reference level, 500MHz and 502MHz.
< –65dBc at 10dB below reference level (100MHz)
<– 55dBc, typically <– 60dBc (Normal sweep, 300Hz to 3MHz RBW)
Spurii
< – 60dBc for signals 10dB below the reference level.
< – 70 dB below the reference level.
Amplitude Markers
Display of absolute and difference amplitudes for both markers in
graticule units (dBm or dBuV) or linear units (mV or uW).
Amplitude Limits (only with Option U02)
Limit Lines from numeric values, or Limit Patterns from Files. Pattern
files are created using PSA-Manager software.
One or two limits on screen. Up to 999 patterns can be stored
Conditions of Above, Below, Inside or Outside creating actions of
beep, stop sweep, log sweep and pulse out
