    Making Measurements Measuring Multiple Signals Measuring Multiple Signals This section provides information on measuring multiple signals. Comparing Signals on the Same Screen Using this analyzer, you can easily compare frequency and amplitude signal differences. For example, measuring radio or television signal spectra. The Delta Marker function allows two signals to be compared when both appear on the screen at the same time.

In this example the next peak is 100 MHz, a harmonic of the 50 MHz signal: • Press [MARKER] > {Peak Search} > {Next Right PK} or {Next Left PK}. To increase the resolution of the marker readings, turn on the NO TE frequency count function.
  • Page 46 Making Measurements Measuring Multiple Signals Resolving Signals of Equal Amplitude In this example a decrease in resolution bandwidth is used in combination with a decrease in video bandwidth to resolve two signals of equal amplitude with a frequency separation of 100 kHz. Notice that the final RBW selected is the same width as the signal separation while the VBW is slightly narrower than the RBW.
  • Page 47 Making Measurements Measuring Multiple Signals As you decrease the resolution bandwidth, you improve the resolution of the individual signals and it also increases the sweep timing. For fastest measurement times, use the widest possible resolution bandwidth. Under factory preset conditions, the resolution bandwidth is coupled to the span.
  • Page 48 Making Measurements Measuring Multiple Signals Resolving Small Signals Hidden by Large Signals This example uses narrow resolution bandwidths to resolve two input signals with a frequency separation of 50 kHz and an amplitude difference of 60 dB. 1 Connect two sources to the analyzer input connector Figure 4-3 on page as shown in 2 Set one source to 300 MHz at –10 dBm.

  • Page 49: Measuring A Low-Level Signal

    Making Measurements Measuring a Low-Level Signal Measuring a Low-Level Signal This section provides information on measuring low-level signals and distinguishing them from spectrum noise. There are four main useful techniques as follows to measure a low-level signal. Reducing Input Attenuation The ability to measure a low-level signal is limited by internally generated noise in the spectrum analyzer.
  • Page 50 Making Measurements Measuring a Low-Level Signal 5 Reduce the span to 1 MHz and if necessary re-center the peak. • Press [SPAN] > 1 > {MHz} 6 Set the attenuation to 20 dB. Note that increasing the attenuation moves the noise floor closer to the signal level.
  • Page 51 Making Measurements Measuring a Low-Level Signal Decreasing the Resolution Bandwidth Resolution bandwidth settings affect the level of internal noise without affecting the amplitude level of continuous wave (CW) signals. Decreasing the RBW by a decade reduces the noise floor by 10 dB. "Reducing Input Attenuation"...
  • Page 52 Making Measurements Measuring a Low-Level Signal Using the Average Detector and  Increased Sweep Time The analyzer’s noise floor response may mask low-level signals. Selecting the instruments averaging detector and increasing the sweep time will smooth the noise and improve the signal’s visibility. Slower sweep times are necessary to average noise variations.
  • Page 53 Making Measurements Measuring a Low-Level Signal Trace Averaging Averaging is a digital process in which each trace point is averaged with the previous sweeps data average for the same trace point. Selecting averaging, when the analyzer is auto coupled, changes the detection mode to sample, smoothing the displayed noise level.

When two signals are present in a non-linear system, they may interact and create third-order intermodulation distortion products that are located close to the original signals.
  • Page 59 Making Measurements Making Distortion Measurements After the performance of the source/analyzer combination has been verified, the DUT (device under test, for example, an amplifier) would be inserted between the directional coupler output and the analyzer input. The coupler used should have a high isolation between the NO TE two input ports to limit the sources intermodulation.

    Key Reference MEAS MEAS In spectrum analysis mode, pressing [MEAS] brings up the menu for a suite of power measurements such as adjacent channel power, occupied bandwidth, and channel power. Occupied Bandwidth (OBW) integrates the power of the spectrum in the displayed green frame. The measurement defaults to 99% of the occupied bandwidth power.
  • Page 107 Key Reference MEAS ACPR The adjacent channel power ratio (ACPR) measures the power ratio between the main channel power and the adjacent channel power. ACPR measures the total power (RMS voltage) in the specified channel. The measurement result reports the ratios of the two adjacent channel powers to the main channel power.
  • Page 108 Key Reference MEAS Channel Power Channel power function measures the power and power spectral density in the channel bandwidth specified. One pair of vertical lines of the displayed green frame indicates the edges of the channel bandwidth. The center frequency, reference level, and channel bandwidth must be set by the user.
  • Page 109 Key Reference MEAS Spectrum Emission Mask (SEM) Spectrum Emission Mask measurement includes the in-band and out-of-band spurious emissions. As it applies to W-CDMA (3GPP), this is the power contained in a specified frequency bandwidth at certain offsets relative to the total carrier power. It may also be expressed as a ratio of power spectral densities between the carrier and the specified offset frequency band.
