Setting Up the List of Ripple Limits to Test
Two tasks are involved in preparing for ripple testing:
• First, set up the analyzer settings to view the frequency of interest.
• Second, set up the analyzer to test over the appropriate frequencies against your
specific limits.
This example will show you how to set up the analyzer to test ripple limits. In this
example, we will be testing the pass band of a bandpass filter where the center frequency
of the filter is approximately 1.8 GHz and has a bandwidth of approximately 2.9 GHz.
Refer to Figure 1-1.

Setting Up Limits for Ripple Testing
This section instructs you on setting up the ripple tests parameters. You must set up the
analyzer to check the DUT at the correct frequencies and compare the measured values
against the maximum allowable ripple value for each frequency band. To do this, you set
up individual frequency bands. You define the stop and start frequency and the maximum
allowable ripple value of each frequency band. You may set up as many as 12 frequency
bands for testing ripple.The frequencybands are combined in a list that is displayedwhile
the ripple frequency bands are being edited.
In this example, we will create one ripple limit (or frequency band) that spans the entire
pass band from 500 MHz to 3.2 GHz. We will also create two additional frequency bands
that when merged, will span the pass band with tighter limits. Using the Ripple Edit
Menu, we will create a ripple limits list on the analyzer that is similar to the following
table.
Table 1-1 Ripple Limits for Ripple Test Example
Frequency BandMinimum FrequencyMaximum FrequencyMaximum Ripple
1500 MHz3.2 GHz2.0 dB
2500 MHz1.85 GHz1.3 dB
31.85 GHz3.2 GHz1.3 dB
Notice that Frequency Band 1 overlaps in frequency the remaining frequency bands.
Whereas, Frequency Bands 2 and 3 are separate bands that cover the same span of
frequency. This can be done to put tighter limits over narrower frequency spans within the
bandpass or to customize the ripple test to meet your specific requirements.

Using Bandwidth Limits to Test a Bandpass Filter
Using Bandwidth Limits to Test a Bandpass Filter
The bandwidth testing mode can be used to test the bandwidth of a bandpass filter. The
bandwidth test finds the peak of a signal in the passband and locates a point on each side
of the passband at an amplitude below the peak (that you specify during the test setup).
The frequency between these two points is the bandwidth of the filter. This bandwidth is
compared to minimum and maximum allowable bandwidths that you specify during the
test setup.
This example shows you how to test the bandwidth of a bandpass filter. In this example,
we will be testing the pass band of a bandpass filterwhere thecenter frequency of the filter
is approximately 321 MHz. Refer to Figure 1-8.

Conversion Loss Using the Frequency Offset Mode
Conversion Loss Using the Frequency Offset Mode
Conversion loss is the measure of efficiency of a mixer. It is the ratio of side-band IF power
to RF signal power, and is usually expressed in dB. The mixer translates the incoming
signal, (RF), to a replica, (IF), displaced in frequency by the local oscillator, (LO).
Frequency translation is characterized by a loss in signal amplitude and the generation of
additional sidebands. For a given translation, two equal output signals are expected, a
lower sideband and an upper sideband.
Figure 1-14An Example Spectrum of RF, LO, and IF Signals Present in a
Conversion Loss Measurement
The following procedure describes the R channel swept IF frequency conversion loss
measurement of a broadband component mixer with power meter calibration. For this
example, we will use an LO frequency of 1 GHz (1000 MHz), an IF start frequency of
100 MHz, and an IF stop frequency of 350 MHz.
1. Set the LO source to the desired CW frequency of 1000 MHz and power level to 13 dBm.

❏ The low pass filter is required to limit the range of frequencies passed into the R
channel input port. The filter is selected to pass the IF frequencies for the
measurement but prevent the LO feedthrough and unwanted mixer products from
confusing the phase-lock loop operation.
❏ A pad is used to isolate the filter and improve the IF port match for the mixer.
Once completed, the display should read 0 dBm.
Setting the Analyzer to the RF Frequency Range
1. While the analyzer is still set to the IF frequency range, set the frequency offset mode
LO frequency from the analyzer by pressing:
System

The LO menu is used to set only the LO CW frequency. All other settings apply when
using the HP/Agilent 8625A external source.
2. To select the converter type and a high-side LO measurement configuration, press:
3. Turn on frequency offset operation by pressing:
Notice in this high-side LO, down conversion configuration, the analyzer's source is
actually sweeping backwards, as shown in Figure 1-17.

How the Analyzer Names These Files Sequentially
When text files are saved, the analyzer generates the file names automatically in the
following format:
txtcss.csv
where:txtis a constant that indicates that this is a text file,
cis the indicator of the channel (1−4) on which the measurement data was
taken (channel-file index number).
ssis a 2-digit, sequential indicator of the measurement (file index number). The
file index number may be numbered from 00−31. As the next measurement is
taken, the file index number is incremented.
If all four channels are making measurements and a save is performed, there
will be four channel numbers that share the same file index number. For
example, the files would be named txt100.csv, txt200.csv, txt300.csv, and
txt400.csv. If a measurement does not include all four channels, unused
channel-file index numbers will not be used by the next measurement.
However, if all of the files that share a file index number are erased, that file
index number will be re-used.

turns bandpass filter bandwidth testing on or off. When
bandwidth testing is on, the analyzer locates the
maximum point of the data trace and uses it as the
reference from which to measure the filter’s bandwidth.
Then, the analyzer determines the two cutoff frequencies
of the bandpass filter. The cutoff frequencies are the two
points on the data trace at a user-specified amplitude
below the reference point. The cutoff frequencies are also
referred to as the N dB Points where “N” is defined as the
number of decibels below the peak of the bandpass that
the filter is specified. (The amplitude is specified using the
softkey.)
The bandwidth is the frequency difference between the
two cutoff frequencies. The bandwidth is compared to the
user-specified minimum and maximum bandwidth limits
(entered using the and
softkeys).
If the test passed, a message is displayed in green text in
the upper left portion of the LCD. An example of this
message is: BW1: Pass, where the “1” indicates the

bandwidth test does not pass, a fail message indicating
whether the bandpass was too wide or too narrow is

turns ripple testing on oroff. When rippletesting is on, the
analyzer sets the lower ripple limit line at the lowest
amplitude point within the frequency band and sets the
upper limit line at the user-specified amplitude above. If
the trace data remains at or below the upper limit line,
that portion of the ripple test passes.If the trace data rises
above the upper limit line within the frequency band, the
test fails. Data within each frequency band is compared
with the defined ripple limit of the band. The ripple test
checks each frequency band using this method. A
maximum of 12 frequency bands can be tested on each
channel. These bands may overlap in frequency. If all of
the channel’s frequency bands pass the ripple test, the
analyzer displays a pass message.
If the test passed, a message is displayed in orange text in
the upper right portion of the LCD. An example of this
message is: RIPL1 PASS, where the “1” indicates the
channel where the ripple test is performed. If the ripple
test does not pass, a fail message is displayed in red text.
An example of this message is RIPL1 FAIL.
displays the ripple value of the selected frequency band.
The ripple value can be displayed in two ways or turned
off.Selecting OFF removes the displayedripple value from
the display. Selecting ABSOLUTE or MARGIN displays
the ripple value. The ripple value is preceded on the
display by an indicator of the selected band. For example,
when the ripple value is preceded by “B2”, this indicates
that the ripple value shown is for Band 2. The frequency
band indicator and ripple value are displayed in the same
color as the pass/fail message for the overall ripple test.
When ABSOLUTE is selected, the display shows the
absolute ripple of the data trace within the frequency
band.
When MARGIN is selected, the display shows the
difference between the maximum allowable ripple and the
absolute ripple valuewithin the frequencyband. When the
margin value is preceded by a plus sign (+), this indicates
that the ripple within the selected frequency band is
passing by the value shown. When the margin value is
preceded by a negative sign (−), this indicates that the
ripple within the selected band is failing by the value
shown.
