Terms Used in This Book

There are many terms used throughout this book, for example “active function block,” that are explained in detail in the Getting Started guide. It is recommended that you read the Getting Started guide first.
The following terms are used to describe each key. Note that a key description may not use all the terms.
State Saved: Indicates what happens to a particular function when the instrument
state is saved (either to floppy disk or the internal c:\ drive). It also indicates whether the current settings of the function are maintained if the instrument is powered on or preset using
Preset
.
Dependencies/ Couplings: Describes dependencies or interactions to other functions or settings in the
analyzer.
Power On Last State or User
Factory Preset: Describes the function settings after a
Factory Preset.
Default Terminator: Indicates the units that will be attached to the numerical value that you
have entered. This default will be used from the front panel, when you terminate your entry by pressing the
Enter key, rather then selecting a
units key. This default will be used remotely when you send the command without specifying any units after your value(s).
Range: Describes the range of the smallest to largest values to which the function
can be set. If you try to set a value below the minimum value, the analyzer defaults to the minimum value. If you try to set a value above the maximum value, the analyzer defaults to the maximum value.
History: Describes the firmware revision history. Only applies after first firmware
release.
Remote Command: Shows the syntax requirements for each SCPI command.
Example: Provides command examples using the indicated remote command syntax.

AMPLITUDE / Y Scale

2.1 AMPLITUDE / Y Scale

Activates the Reference Level function and displays the Amplitude menu keys. These functions control how data on the vertical (Y) axis is displayed and corrected, and control instrument settings that affect the vertical axis.

2.1.1 Ref Level

Enables you to adjust the absolute amplitude represented by the top graticule line on the display (the reference level). Ref in the upper left corner of the display, indicates the current value. The change the reference level, use the front-panel step keys, knob, or numeric keypad.
Amplitude, Y Axis Units setting determines the Reference Level units. To
Key Path:
AMPLITUDE / Y Scale
Dependencies/ Couplings: If you reduce the Attenuation setting, the analyzer may have to lower the
Reference Level to maintain the proper level at the top of the screen. If you then increase Attenuation, the Reference Level does not increase to its previous value.
When the input attenuator is auto-coupled,
Attenuation (Auto), its setting
may be affected by changes in the reference level setting. See
“Attenuation” on page 38.
Reference level is affected by: Attenuation, Preamp, Ext Amp Gain, Reference level offset, Max Mixer Level, Y-Axis Units.
State Saved: Saved in Instrument State
Factory Preset: 0 dBm
Range: Determined by the settings of the input attenuator, reference level offset,
external amplitude gain, and whether the preamp (Option 1DS or 110) is on or off.
Examples:
− 170 dBm to 30 dBm with zero reference level offset
180 dBm to 20 dBm with 10 dB ext amp gain
160 dBm to 40 dBm with 10 dB reference level offset
170 dBm to 0 dBm with preamp on (Option 1DS or 110)

AMPLITUDE / Y Scale
Remote Command:
:DISPlay:WINDow[1]:TRACe:Y:[SCALe]:RLEVel <ampl>
:DISPlay:WINDow[1]:TRACe:Y:[SCALe]:RLEVel?
Example: DISP:WIND:TRAC:Y:RLEV 20 dbm
Sets the reference level to 20 dBm, which displays in the current Y-Axis Units. For example, if the Y-Axis Units are dBµV, then 127 dBµV will be displayed.

2.1.2 Attenuation

Allows you to adjust the input attenuation. Press Atten Step to set the attenuation step so that attenuation will change in 2 dB or 10 dB increments. The analyzer input attenuator reduces the power level of the input signal delivered to the input mixer. If set manually, the attenuator is recoupled when you must use the front-panel numeric keypad.
Attenuation (Auto) is selected. To enter a value below 6 dB,
Attenuation is coupled to Reference Level, so adjusting the Reference Level may change the Attenuation. The analyzer selects an Attenuation setting that is as small as possible while keeping the Ref Level at or below the Max Mixer Lvl setting. The current value is indicated by Atten at the top of the display. A # appears in front of Atten when
(Man)
is selected.
CAUTION To prevent damage to the input mixer, do not exceed a power level of +30 dBm
Attenuation
at the input.
To prevent signal compression, keep the power at the input mixer below 0 dBm (10 MHz - 200 MHz), below 3 dBm (200 MHz - 6.6 GHz), and below –2 dBm (6.6 GHz - 50.0 GHz). With the attenuator set to Auto, a signal at or below the reference level results in a mixer level at or below 10 dBm.
Key Path:
AMPLITUDE / Y Scale
State Saved: Saved in Instrument State
Factory Preset: Auto Coupled, 10 dB (for external amplifier gain of 0 dB)
Resolution/Rounding/ Truncation: The attenuation is resolved to 2 dB increments. If the value is at least
0.5 dB over a value, then the next higher value is selected. Therefore, 10.4 selects 10, while 10.5 selects 12.

2.1.4 Scale Type

Allows you to choose a linear or logarithmic vertical scale for the display and for remote data readout.
The scale type for display and remote data readout may be different from the scale used for averaging processes. For information on the scale used for the averaging process, see
“Avg/VBW Type” on page 81.
When
Scale Type (Log) is selected, the vertical graticule divisions are scaled in logarithmic
units. The top line of the graticule is the Reference Level and uses the scaling per division,
Scale/Div to assign values to the other locations on the graticule.
When
Scale Type (Lin) is selected, the vertical graticule divisions are linearly scaled with
the reference level value at the top of the display and zero volts at the bottom. Each vertical division of the graticule represents one-tenth of the Reference Level.
The Y-axis units used for each type of display are set by pressing

2.1.5 Presel Center

Adjusts the centering of the preselector filter to optimize the amplitude accuracy at the frequency of the active marker. If no marker is on when analyzer turns on the currently selected marker and does a peak search. If a marker is already on, it should be placed on the peak of interest before pressing
Some models of the analyzer contain more than one preselector. The microwave preselector is used for frequencies from 2.85/3.05 GHz (depending on frequency band) to 26.8 GHz. The millimeter preselector is used for frequencies from 26.5 GHz to the maximum frequency of the analyzer (the millimeter preselector is only available in analyzers with a frequency range greater than 26.5 GHz). To center both preselectors, the user must set up and request a a millimeter band. (See
Presel Center in a microwave band, then set up and request a Presel Center in
Presel Adjust for more details.).
The unpreselected high band Option 123 lets you bypass the preselector path. (See

When the preselector path is bypassed, the Presel Center and Presel Adjust keys are unavailable (unless you are using external mixing with preselected external mixers.)
For proper preselector centering, you should make sure that:
if the marker is off, the highest peak onscreen is valid for centering and is in the range
of an active preselector
or
if the marker is on, the signal at the marker is a peak that allows centering and is in the
range of an active preselector.
Other considerations or cautions include:
If a marker is already on, the analyzer attempts the centering at the current marker
position and no peak search is performed. (This allows the user to center the preselector for signals which are not the strongest on-screen signals.)
The preselector path can bypassed. See Input/Output, Microwave Preselector and
Input/output, µW/mmW Preselectors. If it is bypassed, this functionality is not available.
If the signal at the marker position is unstable the algorithm will not function properly.
An example of this would be noise or a noise-like signal like a CDMA digital communications signal.
There is no preselector for signals below 3.05 GHz (in band 0).

2.1.6 Presel Adjust

Allows you to manually adjust the preselector filter center frequency to optimize its response on the signal of interest. This function is not available in frequency band 0. It is for signals 2.85 GHz in band 1 and higher. It is not available if the preselector is turned off. The key also accesses the menu to choose the desired preselector.
For general purpose signal analysis, using filter minimizes the impact of long-term preselector drift.
Presel Center is recommended. Centering the
Presel Adjust can be used instead
to manually optimize the preselector. One application of manual optimization would be to peak the preselector response, which both optimizes the signal-to-noise ratio and minimizes amplitude variations due to small (short-term) preselector drifting.
The analyzer can contain more than one preselector. E4446A, E4447A, and E4448A analyzers have 3 GHz to 26.5 GHz preselector bands and >26.5 GHz preselector bands. The adjustment is preselector specific and the analyzer stores a value for each preselector. Therefore, when the desired frequency range includes frequencies both below and above
26.5 GHz, you must center or adjust each preselector.
The key readout shows which preselector will be adjusted when the key is pressed. The choices are value that is shown on the
[3-26 GHz], [26-50 GHz], and [External]. After performing a Presel Center, the
Presel Adjust key is the offset from nominal of the affected

interpret the results:
Example 1, set the following:
Scale Type (Log) Y Axis Units, dBm Scale/Div, 1 dB Ref Level, 10 dBm
This sets the top line to 10 dBm with each vertical division representing 1 dB. Thus, if a point on trace 1 is on the fifth graticule line from the top, it represents 5 dBm and will read out remotely as 5.
Example 2, set the following:
Scale Type (Lin) Y Axis Units, Volts Ref Level, 100 mV (10 mV/div)
This sets the top line to 100 mV and the bottom line to 0 V, so each vertical division represents 10 mV. Thus, if a point on trace 1 is on the fifth graticule line from the top, it represents 50 mV and will read out remotely as 50.

2.1.9 Ref Lvl Offset

Allows you to add an offset value to the displayed reference level. The reference level is the absolute amplitude represented by the top graticule line on the display. Reference-level offsets are entered by using the numeric keypad or programming commands. The knob and step keys are not active.
Offsets are used when a gain or loss occurs between a device under test and the analyzer input. Thus, the signal level measured by the analyzer may be thought of as the level at the input of an external amplitude conversion device. Entering an offset does not affect the trace position or attenuation value, just the displayed value readouts such as reference level and marker amplitudes.
The maximum reference level available is dependent on the reference level offset. That is, Ref Level Ref Level Offset must be in the range 170 to +30 dBm.
For example, the reference level value range can be initially set to values from 170 dBm to 30 dBm with no reference level offset. If the reference level is first set to 20 dBm, then the reference level offset can be set to values of 50 to +150 dB.
If the reference level offset is first set to 30 dB, then the reference level can be set to values of 200 dBm to 0 dBm. In this case, the reference level is “clamped” at 0 dBm because the maximum limit of +30 dBm is reached with a reference level setting of 0 dBm with an offset of 30 dB. If instead, the reference level offset is first set to 30 dB, then the reference level can be set to values of 140 to +60 dBm.
When a reference level offset is entered, the offset value appears on the left side of the display under Offst (as opposed to frequency offsets which appear at the bottom of the display.) To eliminate an offset, press

Option 110 preamp functions over a frequency range of 100 kHz to 50 GHz. When the preamp is on, an automatic adjustment compensates for the gain of the preamp so that displayed amplitude readings still accurately reflect the value at the analyzer input connector. The Option 1DS preamp is switched off for frequencies above 3 GHz, and the correction is not applied, even though the PA annotation remains on screen. For signal frequencies below 100 kHz, the preamp is not automatically switched out, but signal amplitude roll-off occurs even in the “DC” setting of the RF Coupling control.
The gain of the preamp is nominally 30 dB. This functionality is not available when using external mixing.

An example of a coupled function is Res BW (resolution bandwidth). When Res BW is set to auto, the Res BW is automatically set based on the span setting.
Coupled functions are affected depending on how they are coupled. For example, Video BW is coupled to Res BW, so changing Res BW affects Video BW, but changing Video BW does not affect Res BW. Changing Video BW puts it in manual (instead of auto-coupled). When Video BW is set to

TIP Making Gated FFT Measurements With Your PSA
The process of making a spectrum measurement with FFTs is inherently a “gated” process, in that the spectrum is computed from a time record of short duration, much like a gate signal in swept-gated analysis.
The duration of the time record is 1.83 divided by the RBW, within a tolerance of about 3% for bandwidths up through 1 MHz. Therefore, unlike swept gated analysis, the duration of the analysis is fixed by the RBW, not by the gate signal. Because FFT analysis is inherently faster than swept analysis, the gated FFT measurements can have better frequency resolution (a narrower RBW) than would swept analysis for a given duration of the signal to be analyzed.
FFT analysis in the PSA usually involves making autoranged measurements, and the time required to autorange the FFT can be both long and inconsistent. The PSA hardware automatically sets the
Bypass when any trigger, except Free Run is selected.

Sweep Type is set to Manual:FFT, FFTs/Span becomes
number entered, but it may need to use more due to hardware or software limitations.
An FFT can only be performed over a limited span or segment (also known as the FFT width). Several FFT widths may need to be combined to measure the entire span. The “FFT Width” is (Span)/(FFTs/Span), and affects the ADC Dither function. (See
Couple
).
Auto
FFT measurements require that the signal level driving the A/D converter in the IF be small enough to avoid overloading, and that the gain that controls that signal level remain fixed during the measurement of an entire FFT segment. This constraint can allow higher dynamic ranges in swept mode in some cases, but increasing FFTs/Span can restore that dynamic range to FFT measurements, at the expense of losing some of the speed advantages of the FFT.
For example, in pulsed-RF measurements such as radar, it is often possible to make high dynamic range measurements with signal levels approaching the compression threshold of the analyzer in swept spans (well over 0 dBm), while resolving the spectral components to levels below the maximum IF drive level (about –8 dBm at the input mixer). But FFT processing experiences overloads at the maximum IF drive level even if the RBW is small enough that no single spectral component exceeds the maximum IF drive level. If the user reduces the width of an FFT using the FFTs/Span function, an analog filter is placed before the ADC that is about 1.3 times as wide as the FFT segment width. This spreads out the pulsed RF in time and reduces the maximum signal level seen by the ADC. Therefore, the input attenuation can be reduced and the dynamic range increased without overloading the ADC.
Further improvement in the dynamic range is possible by changing the ADC gain. In swept analysis in PSA, the gain is normally autoranged such that it can track the signal power as the analyzer sweeps through CW-like signals. Since FFT processing cannot autorange the gain within the measurement of a single FFT segment, the autoranging advantage is lost for single FFT measurements. But if the segments are reduced in width by using more FFTs/Span, then individual FFT segments can use higher gains, improving the dynamic range.
Additional information about selecting FFTs/Span can be found in a product note, "PSA Series Swept and FFT Analysis," literature number 5980-3081EN, available on-line through http://www.agilent.com.

2.3.5 Avg/VBW Type

Displays the functions that enable you to automatically or manually choose one of the following averaging scales: log-power (video), power (RMS), or voltage averaging.
NOTE When you select log-power averaging, the measurement results are the
average of the signal level in logarithmic units (decibels). When you select power average (RMS), all measured results are converted into power units before averaging and filtering operations, and converted back to decibels for displaying. Remember: there can be significant differences between the average of the log of power and the log of the average power.
The following are the averaging processes within a spectrum analyzer, all of which are affected by this setting:
Trace averaging (see BW/Avg) averages signal amplitudes on a trace-to-trace basis.
Average detector (see Detector, Average) averages signal amplitudes during the time or
frequency interval represented by a particular measurement point.
Noise Marker (see Marker Noise) averages signal amplitudes across measurement points
to reduce variations for noisy signals.
VBW filtering adds video filtering which is a form of averaging of the video signal.
When manual is selected, the type is shown on the left side of the display with a #. When auto is selected, the analyzer chooses the type of averaging. When one of the average types is selected manually, the analyzer uses that type regardless of other analyzer settings, and

Displays the menu keys that select the detector.

2.4.1 Detector

This menu allows you to select a specific type of detector, or choose Auto to let the instrument select the appropriate detector for a particular measurement.
When discussing detectors, it is important to understand the concept of a trace “bucket.” For every trace point displayed in swept and zero-span analysis, there is a finite time during which the data for that point is collected. The analyzer has the ability to look at all of the data collected during that time and present a single point of trace data based on the detector mode. We call the interval during which the data for that trace point is being collected, the “bucket.” The data is sampled rapidly enough within a “bucket” that it must be reduced in some fashion to yield a single data point for each bucket. There are a number of ways to do this and which way is used depends on the detector selected. Details on how each detector does this are presented below.
In FFT analysis, the bucket represents just a frequency interval. The detector in an FFT mode determines the relationship between the spectrum computed by the FFT and the single data point displayed for the bucket.
When the
Detector choice is Auto, the detector selected depends on marker functions, trace
functions, and the trace averaging function.
See “Auto Rules For Detector Selection” on page 90 for information on the
Auto detector
selection.
When you manually select a detector (instead of selecting
Auto), that detector is used
regardless of other analyzer settings.
The detector choices are:
Normal displays the peak of CW-like signals and maximums and minimums of
noise-like signals.
Average displays the average of the signal within the bucket. The averaging method
depends upon
Peak − displays the maximum of the signal within the bucket.

MIL Peak the same as the Peak detector but uses MIL related bandwidths.
Because they may not find the true peak of a spectral component, neither average nor sample detectors measure amplitudes of CW signals as accurately as peak or normal, but they do measure noise without the biases of peak detection.

2.4.1.1 Auto
The system selects normal detection as the default, but if a condition arises where a different type of detection scheme would be better utilized, the system uses the alternate scheme. For example, when in Auto mode, the Marker Noise function uses Average detection because the system determines that the average detector has better speed or variance tradeoffs for noise-type signals.

For each interval (bucket) in the trace, Peak detection displays the highest amplitude within the interval. Peak detection is used for CW measurements and some pulsed-RF measurements. For swept analysis, peak detection basically obtains the maximum video signal between the end of the previous bucket and the end of the current one. Gain is increased to compensate for the effects of faster sweep rates, to keep the displayed value accurate. For FFT analysis, the highest spectral amplitude is displayed, even if that peak amplitude falls between samples of the spectrum computed in the FFT process.

2.4.1.5 Sample
The sample detector displays the instantaneous level of the signal at the center of the interval (bucket) represented by each trace point.
Sample detection is primarily used to display noise or noise-like signals.
Sample detection is not best for amplitude measurements of CW-like signals for two reasons. First, the peak response to a signal can occur between samples, so unless the Span to RBW ratio is lower than usual, the highest sample can be well below the peak signal amplitude. Second, for the high sweep rates normally used, the peak response of the RBW filters is up to –0.5 dB. This sweeping error is compensated when using the peak and normal detectors by changing the overall gain. But the gain is not changed when in the sample detector, because to do so would cause errors in the response to noise.
