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)

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.

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

Y Axis Units. The analyzer

remembers the settings for both Log and Lin.

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

AMPLITUDE / Y Scale

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).

• With Input Mixer (Ext) selected and the Mixer Type set to Presel (preselected), Presel

Center

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

preselector’s frequency.

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

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

functions over a frequency range of 100 kHz to 3 GHz. 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

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

2.3.3 VBW/RBW

Selects the ratio between the video and resolution bandwidths in a 1, 3, 10 sequence. Video
bandwidth wider than resolution bandwidth (VBW/RBW ratio > 1.000), provides the best
peak measurements of signals such as wideband radar pulses. VBW narrower than RBW
(VBW/RBW ratio < 1.000) reduces the variance of noise-like signals and makes spectral
components close to the noise floor easier to view. The knob and step keys change the ratio
in a 1, 3, 10 sequence. If the numbered keys are used, the VBW/RBW ratio will be rounded
to the nearest 1, 3, or 10 response. Pressing

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

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.

• Negative Peak − displays the minimum of the signal within the bucket.

• Quasi Peak − a fast-rise, slow-fall detector used in making CISPR compliant EMI

measurements.

• EMI Average − displays the instantaneous level of the signal at the center of the bucket,

measurements.

• EMI Peak − the same as the Peak detector but uses CISPR related bandwidths.

• 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.

The detector in use is indicated on the left side of the display, just below Reference level.
The designators are:

• Norm − Normal detector

• Avg − Average detector

• Peak − Peak detector

• Samp − Sample detector

• NPk − Negative Peak detector

• EmiQP − Quasi Peak detector

• EmiAv − ΕMI Average detector

• EmiPk − Peak detector with CISPR bandwidths

• MILPk − Peak detector with MIL bandwidths

If the detector has been manually selected, a # appears next to it.

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.

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.
