    Pulse Analyzer (Option 421) 2-4 Pulse Measurements Finding the Reference Level Instants Instants are a specific time value within a waveform time duration. They are typically referenced relative to the initial instant of the waveform. The following sections describe how the pulse measurements are determined (see Figure 2-7 Figure...
  • Page 14 2-4 Pulse Measurements Pulse Analyzer (Option 421) Finding Pulse Duration and Period The pulse duration is determined by using the positive and negative transitions as describe above to check if it is a valid pulse. If so, then any pulse duration reference levels (50%) are verified to exist within the positive/negative transition.
  • Page 15 Pulse Analyzer (Option 421) 2-4 Pulse Measurements Finding the Wave Amplitude The wave amplitude is found by subtracting the amplitude of the lower state level from the amplitude of the upper state level in dB units.

  • Page 19: Connecting A Signal Source

    Pulse Analyzer (Option 421) 2-7 Connecting a Signal Source Connecting a Signal Source The basic setup starts with connecting a signal source to the RF In port of the instrument. For over-the-air measurements, connect an antenna that is appropriate for the frequency range to be measured. For direct conducted measurements, ensure the RF source does not over power the input of the analyzer.

    Pulse Analyzer (Option 421) 2-9 Setting Amplitude Parameters Setting Amplitude Parameters Amplitude-related parameters are set using the “AMPLITUDE Menu” on page 2-17. Setting Amplitude Reference Level The amplitude reference level is typically an absolute reference level set at the top of the graticule for the power level being measured.

  • Page 22: Preamplifier

    2-9 Setting Amplitude Parameters Pulse Analyzer (Option 421) Preamplifier The preamplifier can be turned on and off by toggling PRE AMP via the status panel or the AMPLITUDE menu. Figure 2-16 shows the noise floor with the preamplifier off (1) and on (2). Note that when the preamplifier is turned on, the noise floor drops significantly and a low-level signal is exposed.

  • Page 24: 2-10 Setting Bandwidth Parameters

    2-10 Setting Bandwidth Parameters Pulse Analyzer (Option 421) 2-10 Setting Bandwidth Parameters Bandwidth parameters are set using the “BANDWIDTH Menu” on page 2-19. Resolution Bandwidth Resolution Bandwidth (RBW) determines frequency selectivity. The spectrum analyzer traces the shape of the RBW filter as it tunes past a signal. The choice of resolution bandwidth depends on several factors. Filters take time to settle.

  • Page 25: Bandwidth Menu

    Pulse Analyzer (Option 421) 2-10 Setting Bandwidth Parameters Auto coupling VBW links the video bandwidth to the resolution bandwidth so that VBW varies in proportion to RBW. If manual VBW coupling is selected, the VBW label at the bottom of the graph is prefixed with the “#” symbol and video bandwidth is set independently of resolution bandwidth.

  • Page 34: Marker Functions

    2-13 Setting Up Markers (Pulse Viewer Mode) Pulse Analyzer (Option 421) Marker Functions Noise Markers Noise Markers use an averaging routine applied to multiple data-point groups to calculate the readout, which is typically comparable to using 1 Hz bandwidth filtering. Because the noise marker routine uses groups of data points for the calculation, the noise marker should not be placed in close proximity to measurable signals.
