Narda
Individual: separately defined for each individual service
Root mean square value (RMS), RMS (integration time ≈1/RBW)
Summarizes all measurement values for frequency gaps within the list of channels and shows
the total value for all gaps. "Others" can be switched ON or OFF.
NRA-2500
Selective level measurement at a selectable frequency (see frequency range)
RMS (averaging time selectable from 480 ms up to 30 min)
Steep cut-off channel filter (app. raised cosine)
100 Hz to 32 MHz (in steps of 100, 125, 160, 200, 250, 320, 400, 500, 640, 800, 1000,...,
10 MHz, 13.333 MHz, 16 MHz, 20 MHz, 26.666 MHz, 32 MHz)
Peak ACT: Displays the actual peak value
Peak MAX: Max hold function for peak values
RMS ACT: Averaging over a defined time period (0.48 seconds to 30 min)
RMS MAX: Max hold function for RMS values
NRA-2500
Selective level measurement vs. time at a selectable frequency (see frequency range)
100 Hz to 32 MHz (in steps of 100, 125, 160, 200, 250, 320, 400, 500, 640, 800, 1000,...,
10 MHz, 13.333 MHz, 16 MHz, 20 MHz, 26.666 MHz, 32 MHz)
Steep cut-off channel filter (app. raised cosine)
Off, 0.01 Hz to 32 MHz (depending on the selected CBW)
Act: Instantaneous magnitude value
I, Q or I&Q: In-phase demodulated signal, Quadrature demodulated signal or both
MAX: Maximum value within the time resolution interval (corresponds to peak detector).
AVG: Average value within the time resolution interval (corresponds to RMS detector).
MIN: Minimum value within the time resolution interval.
Duty cycle (ratio of average power to maximum power)
Free run, single, multiple, manual start, time controlled
Programmable trigger level, trigger slope and trigger delay
