Book Organization

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.

NOTE The front- and rear-panel features, along with the numeric keypad and

alpha-numeric softkey fundamentals are illustrated and described, in
your Getting Started guide.

What is in This Book

• Book Organization - describes the organization of this book.

• Instrument Functions - provides information about the front-panel and lower-level

key functions of your analyzer and their associated programming commands. This
information is organized alphabetically by the front-panel key name. For your
convenience, the instrument functions information has been divided into three separate
chapters; Instrument Functions: A-L, Instrument Functions: M-O,andInstrument
Functions: P - Z.

• Programming Fundamentals - provides information on SCPI and C programming

language basics, and on using GPIB and LAN.

• Using the STATus System - provides information about the instruments internal

status monitoring system with information on how to monitor the status using a remote
program and descriptions of all the available commands.

• Menu Maps - illustrates the menu structure of the front-panel and lower-level keys.

Refer to this chapter to identify the lower-level softkeys associated with the front-panel
keys.

TermsUsedinThisBook

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

Fact o r y Pres e t: 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

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.

2.0.1 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.

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 50.

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) 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

−160dBmto40dBmwith10dBreferenceleveloffset

−170 dBm to 0 dBm with preamp on (Option 1DS)

Remote Command:

: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, t h e n 1 2 7 d B µVwillbe
displayed.

2.0.2 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 Attenuation (Auto) is selected. To enter a value below 6 dB,
you must use the front-panel numeric keypad.

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

is selected.

(Man)

CAUTION To prevent damage to the input mixer, do not exceed a power level of +30 dBm

at the input.

Attenuation

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. Value setting a logarithm:

if 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.

Range: 0 dB to 70 dB

2.0.6 Presel Adjust

Allows you to manually adjust the preselector filter frequency to optimize its response on
the signal of interest. This function is only available when measuring signals ≥2.85 GHz in
band 1 and higher bands.

For analyzers that have both millimeter wave and microwave types of bands (E4448A and
E4446A analyzers) the adjustment is band specific. If the currently active marker, or the
center frequency, is in one of the four lower bands (bands 1 to 4) the preselector adjustment
specified is used for the microwave bands. However, if the active marker or center
frequency is in one of the two upper bands (bands 5 to 6), then the preselector adjustment
is applied for those millimeter bands.

NOTE In the 26.4 to 26.8 GHz range there is an overlap between bands 4 and 5 that

causes the boundary between these two bands to shift dynamically. You must
be aware that the preselector adjustment is applied to the correct band
(either 4 or 5) based on the current settings of the analyzer.

When the preselector adjustment is being changed, the active function area of the display
shows a third line (mm-wave bands preselector,orMW bands preselector)dependent
on the preselector applied. The preselector applied is determined by the analyzer settings
of the start, stop, and marker frequency settings as shown below. Note that applied
preselector will be notated in the active function block of the display.

2.0.7 Y Axis Units

Displays the menu keys that enable you to change the vertical (Y) axis amplitude units.
The analyzer retains the entered
scale types. For example, if Scale Type has been set to Log,andyousetYAxisUnitsto dBm,
pressing Scale Type (Log) sets the YAxisUnitsto dBm.IfScale Type has been set to Lin and
you set YAxisUnitsto Volt s , pressing Scale Type (Lin) sets the YAxisUnitsto Vo lt s. Pressing

Remote Command Notes: The settings of Y Axis Units and Scale Type, affect how the

units are returned, so you must know what the Y-Axis units are to
interpret the results:

Example1,setthefollowing:

ScaleType(Log)
YAxisUnits,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.

Example2,setthefollowing:

ScaleType(Lin)
Y Axis Units, Volts
Ref Level, 100 mV (10 mV/div)

Instrument Functions: A - L

56 Chapter2

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.

2.0.8 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 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

2.0.9 Int Preamp

(Option 1DS only.) Turns the internal preamp on and off. The preamp functions over a
frequency range of 100 kHz to 3 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 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 (PSA) or 20 dB (ESA).

Coupled functions are functions that are linked/dependent on other functions. Pressing

Auto Couple displays some of the most important coupled analyzer functions.

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 auto ranged
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.

The width of a single FFT measurement can be up to 10 MHz, so gated FFT
measurements can only be made for spans of 10 MHz or less.

To make a gated FFT measurement, set the analyzer as follows.

1. Press Auto Couple, FFT & Sweep to select ManuaL: FFT.

2. Set the resolution bandwidth to 1.83 divided by the required analysis time,

or higher, by pressing BW/Avg, Res BW.

3. Set the trigger source to the desired trigger, by pressing Trig.

4. Set the trigger delay to observe the signal starting at the required time

relative to the trigger. Negative delays are possible, by pressing Tr ig, Tr ig

2.1.2.5 FFTs/Span

Displays and controls the number of FFT segments used to measure the entire Span. This
key is inactive (greyed out) unless

Sweep Type has been set to FFT. If Sweep Type is set to

Auto and FFTs are selected, FFTs/Span is still greyed out, and the number of FFTs
automatically selected is shown. If Sweep Type is set to Manual:FFT, FFTs/Span becomes
available. Press FFTs/Span and an integer can be entered. The analyzer will try to use the
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

Auto Couple).

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
beforetheADCthatisabout1.3timesaswideastheFFTsegmentwidth.Thisspreadsout
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 dynamic range is possible by changing the ADC gain. In swept
analysis in PSA, the gain is normally auto ranged 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 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 online

RBW, the equivalent 6 dB bandwidth of any RBW filter can be determined
using the following formula: 6dBRBW= 3dBRBWx 1.414. For example, if a

2.3.1 Detector

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.” Thus, a trace is more than a series of single points. It is actually a
series of trace “buckets.” The data may be sampled many times within each bucket.

In swept analysis, the time interval of data collection for a display bucket also represents a
frequency interval. In FFT analysis, the bucket represents just a frequency interval. The
detector 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 97 for information on the Auto detector

selection.

When you manually selected a detector (instead of selecting

Auto), that detector is used

regardless of other analyzer settings.

The detector choices are:

• The Sample detector displays the instantaneous level of the signal at the center of the

bucket represented by each display point.

• The Normal detector displays the peak of CW-like signals and maximums and minimums

of noise-like signals.

• The Average detector displays the average of the signal within the bucket. The averaging

method depends upon Avg Type selection (voltage, power or log scales).

• The Peak detector displays the maximum of the signal within the bucket.

• The Negative Peak detector displays the minimum of the signal within the bucket.

Det/Demod

Because they may not find a spectral component's true peak, 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. If the detector has been
manually selected, a # appears next to it.

TIP RMS Detection

To measure the average power (RMS voltage) in each display point, set

Detector to Average,andverifythatAv g/VBW Type is set to Pwr Avg (RMS).

2.3.1.1 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 a better
speed/variance trade-off for noise-type signals.

Figure 2-1, which shows a decision tree of how detection type is determined.

2.3.1.2 Normal

Displays the peak-detected level in the interval (bucket) being displayed when the signal is
CW-like. If the signal is noise-like (within a bucket the signal both rose and fell), the even
bucket shows the peak (maximum) within a two-bucket interval, and the odd bucket shows
the negative peak (minimum). Gain is increased to compensate for the effects of faster
sweep rates, to keep the displayed value accurate.

2.3.1.3 Average

For each interval (bucket) in the trace, Average detection displays the average of all
samples within the interval using one of the following averaging methods:

• log (also known as video)

• power (also known as RMS)

• voltage envelope

To explicitly set the averaging method, use the

BW/Avg, Avg/VBW Type key. The combination

of the average detector and the power method is equivalent to what is sometimes referred
to as “RMS detection.” When the method (

Avg/VBW Type)issettoPwr Avg,andDetector is set

to Average, the RMS method is selected.

Average is selected, Avg appears on the left side of the display.

2.3.1.4 Peak

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 last bucket and the start of the next 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.

Peak is selected, Peak appears on the left side of the display.

2.3.1.5 RMS (Remote Command Only)

Selects the Average Detector. If

BW/Avg, Avg/VBW Type is set to Auto (or Pwr Avg) this will yield

the RMS voltage (average power) for each trace point. (See 3.4.1.3, Average)

Key Path: There is no key selection for this setting, but you can access it by using

Average Detector (see “Average” on page 98).

“Detector” on page 95.

2.3.1.6 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.
