    © 2015 All rights reserved OSCILLOSCOPE SCREEN Oscilloscope screen is another great feature of the SMΩRF. Serves for waveform inspection, overshoots visualization, lead and tail time measurements etc etc … It mimics standard digital bench oscilloscope but since SMΩRF is an instruments for RF power measurements, it is optimized for this job, and adds some features you will not find on any standard digital oscilloscope.

This choice should be used when smoothness of provided waveform is more important than peaks. MIN-MAX • It is a special acquisition type providing two waveforms on display. Lower is related to minimal value of the measured signal, higher to peak value of measured signal.
  • Page 29: Spectrum Screen

    © 2015 All rights reserved SPECTRUM SCREEN Spectrum screen is similar screen to the Oscilloscope screen but visualizes data in the frequency domain instead of oscilloscope's time domain. It uses SMΩRF's peak detector data and with help of Digital Signal Processing (DSP) translates them into frequency domain using Fast Fourier Transformation (FFT).

  • Page 31: Auto Mode

    © 2015 All rights reserved AUTO MODE AUTO mode is a special operating mode of the SMΩRF which can be applied for any single sensor screen. In AUTO mode, meter makes automatic sensor focus to the first sensor from which detects power. Unfocused sensor is ignored and alarms for this sensor are not generated.
  • Page 32: 2Tx Screen

    © 2015 All rights reserved 2TX SCREEN 2TX screen is a DUAL sensor screen, providing simultaneous measurements for both sensor. This screen is available in TWO INDEPENDENT RADIOS AND SENSORS meter mode, and is suitable for setups with two radios when it is normal that both radios transmit at the same time and it is necessary to monitor power of both radios simultaneously.

    © 2015 All rights reserved 4IN SCREEN 4IN is a very special screen designed to use SMΩRF as a four channel level/phase meter without any sensors. This screen is available only in special, 4 DIRECT INPUTS meter mode. The 4IN screen is a big help for low level measurements. Accurate measurements of amplitude and phase on four inputs simultaneously is unique feature of the SMΩRF you can find only on 4 channel oscilloscopes which...
  • Page 36 © 2015 All rights reserved Bottom line: If you are going to measure just one signal, use IN1 or IN3 input on the SMΩRF. If measured level is below the frequency lock level (-35dBm), rise amplitude first until it locks.

  • Page 50 © 2015 All rights reserved Nature of the coaxial cables is that they have monotone (but not linear) attenuation characteristic, with rising frequency attenuation rises. If cables connecting the SMΩRF are not absolutely same in the electrical length, also some phase shift is introduced. Both this parameters have huge impact to accuracy and need to be eliminated.
