Scaling the axis automatically has the advantage that the application automatically selects the ideal scale for the current measurement results. When you select the "Auto" scale mode, the R&S FSPN adjusts the scale of the axis during the measure- ment.
Page 105: Frequency
In addition, you can perform a single automatic scale adjustment with the "Auto Scale Once" feature. When you do so, the R&S FSPN selects the ideal scale for the current measurement results, but will not update the scale for the next measurement.
Page 106 Defining the signal frequency The "Signal Frequency" is the frequency the signal is transmitted with. You can define it manually in the corresponding input field or let the R&S FSPN search for the signal frequency in an automatic frequency search (turn on the "Auto Search"...
Page 107 "Signal Count" feature. In that case, the R&S FSPN tunes to the frequency you have entered and measures its phase noise characteristics, even if no signal is present. Turning off the frequency counter can improve measurement speed, however.
Page 108 367 [SENSe:]TIME:STOP Measuring low frequency and low level signals The R&S FSPN provides functionality to measure the phase noise of signals with a low frequency and / or a low signal level. ● Low frequencies can be measured by applying the low pass filter.
Page 109 ● "Low": The R&S FSPN uses an IF of 15 MHz. Therefore, the DC offset of the I/Q mixers does not limit the sensitivity. It is recommended to use this level setting for signal levels below -20 dBm.
Page 110: Noise Measurement Configuration
® Common Measurement Settings R&S FSPN Noise Measurement Configuration Multicarrier signals ← Measuring low frequency and low level signals You can also use the low pass filter when you want to measure the phase noise of a single carrier in a multicarrier signal. In that case, the cutoff frequency of the filter should be the same as the carrier spacing.
Page 111: Noise Configuration
® Common Measurement Settings R&S FSPN Noise Measurement Configuration The main issue in this context is the resolution bandwidth (RBW) and its effect on the measurement time. In general, it is best to use a resolution bandwidth as small as pos- sible for the most accurate measurement results.
Page 112 ® Common Measurement Settings R&S FSPN Noise Measurement Configuration Sweep/Average Count ....................115 Selecting the sweep direction..................115 Working with the half decade configuration table............115 Estimating the measurement time Based on the parameters you have defined for the noise measurement, the application estimates the total measurement time required to measure the noise characteristics over all half decades.
Page 113 When this is not the case, the R&S FSPN stops calculating results, even when the selected number of operations has not yet been reached. This is thus a good tool to speed up the mea- surement.
Page 114 When the distance between those two traces exceeds the threshold in any given half decade, the R&S FSPN stops measuring in this half decade and resumes with the next one. Example: The number of operations in a half decade is 30. When optimization is on, and the results do not improve any more after 20 operations, the application stops measure- ments in that half decade.
Page 115 Remote command: on page 364 [SENSe:]SWEep:COUNt Selecting the sweep direction The sweep direction selects the order in which the R&S FSPN measures the half deca- des. For the reverse sweep ("Sweep Forward" = "Off"), the measurement sequence is: ● Analysis of half decades > 30 MHz ●...

Page 117 Defining the integration range You can define up to 10 integration ranges on different traces. By default, the R&S FSPN integrates over the entire frequency range defined for the measurement (Range = "Meas"). You can, however, also define custom integration ranges (Range = "Manual").
Page 118 Frequencies must be entered in ascending order and must not overlap. When you save the filter, the R&S FSPN uses the name of the weighting filter as the file name. If a weighting filter of the same name already exists, the R&S FSPN asks before it overwrites the existing file.
Page 119: Spot Noise Information
119 Displaying spot noise information By default, when you perform a measurement, the R&S FSPN displays the spot noise information in the diagram area. You can turn off the displayed spot noise information any time, for example if you want a better view of the measurement results.

Page 127: Sweep Configuration
® Common Measurement Settings R&S FSPN VCO Characterization Configuration Pushing measurements are possible when you connect the "Sweep Source" to the supply port of the DUT and the "Fix Source" to the tune port of the DUT. A pushing measurement typically measures the influence of a swept supply source on the DUT characteristics.
Page 128 129 Defining the sweep range The R&S FSPN characterizes a DUT by applying a series of (tuning) voltages or cur- rents to the DUT. Each voltage or current is a measurement point. The number of mea- surements performed during a VCO characterization therefore depends on the number of measurement points.
Page 129: Trace Configuration
Note that only discrete values for the frequency resolution are supported. If you enter a frequency resolution that is not supported, the next available frequency resolution is selected. For example, if you enter 200 Hz, which is not supported, the R&S FSPN selects 1 kHz instead.

Narrowband mode works over the complete frequency range supported by your R&S FSPN. If you select a span > 40 MHz in the specified frequency range, the R&S FSPN auto- matically selects the wideband mode. If you select a span < 40 MHz, the R&S FSPN automatically selects the narrowband mode.

Page 134 ● "I/Q Power" A measurement starts when the R&S FSPN detects a rise or fall of the signal level within the demodulation bandwidth (span). This trigger source is only available for narrow measurement mode.
Page 135 - this happens several times, until the DUT is stable. Without a drop-out time, the R&S FSPN would start a measurement each time the fre- quency falls below the trigger frequency. With a drop-out time, however, only the first trigger event initiates a measurement.
Page 136: Data Acquisition
Defining the measurement time The measurement time defines for how long the R&S FSPN measures the transient response. The R&S FSPN always matches the scale of the x-axis of the result displays to the measurement time. Remote command: on page 365 [SENSe:]SWEep:TIME User Manual 1179.4363.02 ─...

The reference level is the expected level of the signal you are measuring. Because the hardware of the R&S FSPN is adapted according to this value, it is rec- ommended that you set the reference level close above the expected maximum signal level.

Markers are used to mark points on traces, to read out measurement results and to select a display section quickly. R&S FSPN provides 16 markers per display window. In the Phase Noise application, markers across measurement windows are independent from each other - thus you can move a marker in one window without moving it in another window.

® General Instrument Setup R&S FSPN Alignment 9 General Instrument Setup Access: [SETUP] Some basic instrument settings can be configured independently of the selected oper- ating mode or application. Usually, you will configure most of these settings initially when you set up the instrument according to your personal preferences or require- ments and then only adapt individual settings to special circumstances when neces- sary.
Page 211 ® General Instrument Setup R&S FSPN Alignment If you start a self-alignment remotely and then select the "Local" softkey while the alignment is still running, the instrument only returns to the manual operation state after the alignment is completed. During self-alignment, do not connect a signal to the RF input connector. Running a self-alignment with a signal connected to the RF input can lead to false measurement results.

210). Automatic self-alignment During installation of the R&S FSPN firmware, you can configure an automatic self- alignment to be performed directly after installation. In addition, you can activate a pre- ceding warmup time before self-alignment, which is strongly recommended. If you do not activate this option, make sure the instrument has reached its operating tempera- ture before installing the firmware.
