Overview
This chapter contains the following information:
a Key Operation Overview
uw Numerical Entries
m Character Entries
After chapter 2, the procedural steps do not contain as much detailed
information. Therefore, you should read this chapter to understand
the basic rules of analyzer’s operation.
Key Operation Overview
Hardkeys and Softkeys
There are two types of front-panel keys; hardkeys and softkeys. Most
hardkeys that have a label display function menus on the right side of
the display. These function menus are also called softkey menus,
Softkey menus list functions other than those accessed directly by the
hardkeys. To activate a function that is on a softkey menu, press the
key located to the right of the displayed function label.
This manual uses the following conventions:
Indicates a hardkey
Softkey Indicates a softkey
Toggle Keys Some softkeys toggle menu settings. On a softkey label, the currently
active setting is displayed in high intensity and upper case characters.
The inactive setting is displayed in low intensity and lower case
characters.
This manual shows a toggled setting as follows:
m Toggle DUAL CHAN on OFF to ON off.
This line means that the dual channel function is currently OFF. You
turn it ON by pressing the corresponding softkey. The resulting upper
case expression, ON, shows that the function is now active (ON).
For more information about each hardkey and softkey, see the
Function Reference manual.

Numerical Entries
Notes
A numerical data entry is preceded by some function settings. For
example, before entering a center frequency you must specify the
center frequency value. The analyzer provides the following three
ways to enter numerical data:
Using Description
Numerical keys (0) .. (9) Enters numerical data directiy and
terminates the entry using the units
terminator keys. This capability is useful
when you know the value you must enter.
For example, to enter ! MHz, press (1) (M/u).
(1) and (7) key Increments or decrements the settings. This
is useful for changing settings broadly.
Rotary knob 6 Changes settings continuously. This is useful
if you want to change the setting while
verifying changes on the display.
You can use following techniques when entering numerical data:
mw If you enter a wrong character, press to erase the last
character entered.
mw If you want to clear the current entry, press (Entry Off).

To Narrow the Span Setting
1. Press (Search).
2. Press SEARCH:PEAK to place the marker on the carrier.
3. Toggle SIGNAL TRK on OFF to ON off
4. Narrow the span setting. See the “To Set the Frequency Span”
procedure.
When you narrow the span setting substantially, the test signal
can disappear from display. This happens because of the difference
between the displayed and actual frequencies. For example, when the
span setting is set to full span, the displayed test signal frequency
has an error of approximately 2 MHz because of its resolution {1.8
(Hz/800). If you narrow the span setting to less than the error
frequency, the test signal can be lost from the display.

The signal track function allows you to avoid this situation. When
signal track is enabled, the analyzer narrows the span setting while
centering the test signal as you narrow the span setting. Therefore,
the test signal is placed in the center of the grid.

The following figures show an example of narrowing the span with
the signal track function. The actual signal frequency is 1.00001 GHz.
When the center is fixed and the span is 10 kHz, the signal is out of
display. The signal track function tracks the signal by changing the
center frequency, and keeps displaying the signal in the center of the
display.

Step 6: Tuning the Settings
This step provides the bandwidth settings. The RBW setting affects
the resolution of the frequency and lowers the displayed noise floor.
The video bandwidth setting reduces noise variation.

To Set the Resolution Bandwidth (RBW)
1. Press (Bw/Avg).
2. Change the RBW setting by using (1), (I), or the ©).
If the internal IF filter is wider than the difference of the adjacent
signals, the analyzer cannot separate them. You must set the
Resolution Bandwidth (RBW) narrower to make sure the analyzer
can recognize each signal. For more information about RBW, see the

Narrowing the RBW reduces the noise power per display point. As a
result, the displayed noise floor is down and the lower level signal is
displayed.
For example, the trace of a 20 kHz amplitude modulated signal
conceals sidebands in the skirt of the carrier trace when the RBW is
10 kHz. If you set the RBW to 1 kHz, the carrier and sidebands are
split completely and the displayed noise floor is down.

When the target signal and the noise are hard to distinguish because
of noise variation, narrow the video bandwidth. This reduces the
noise variations and makes the signal clearly visible. However, if the
video bandwidth is narrowed, the sweep takes more time.
The allowable VBW setting is 1/1, 1/3, 1/10, 1/30, 1/100, and 1/300 of
the current RBW setting.

Step 7: Performing Calibration
This step provides procedures for the reference level calibration.
Performing the reference level calibration improves the level
accuracy.
E To perform the reference level calibration
m To use the external reference
# To turn off the calibration
To Perform the Reference Level Calibration
1. Wait at least 30 minutes after the analyzer is turned on. This
warming up period is required to meet the analyzer's specifications.
2. Attach the N(m)-BNC(f) adapter (furnished) to an input (S, R, A, or
B). (See Figure 2-15.)
3. Connect the CAL OUT output and the selected input using the BNC
cable (furnished).
4. Press (Meas). Then select the input (that the cable is connected to)
by pressing 8, К, А ог В.
5. Press (Cal).
6. Press EXECUTE LVL CAL.
The analyzer automatically changes the frequency setting to measure
the CAL OUT signal. When the reference level calibration is
completed, all measurement settings are restored.
After the calibration is completed, “Cor” appears on the left side of
the grid.
To obtain a higher level measurement accuracy, perform the reference
level calibration just before reading the measured value. If you
change the setting of the RBW or the attenuator, you must perform
the reference level calibration again. The analyzer stores the
calibration data individually for each of the inputs,
The error terms that are canceled by the reference level calibration
are described in chapter 12 of the Function Reference manual.

3. Read the marker value displayed on the upper right of the display.
If you want a more accurate frequency reading of the target signal,
set the span and the RBW as narrow as possible.
The readout resolution of the frequency is determined by the setting
of the frequency span, the number of points (NOP), and the resolution
bandwidth (RBW). The resolution is the larger value between
SPAN/(NOP—1) and RBW. For example, when the frequency span is 10
MHz, the NOP is 801, and the RBW is 10 kHz, the readout resolution
is approximately 12.5 kHz.

m For the target signal:
cl Signal width (7)
cl Signal delay (SD)
un For the trigger signal:
2 Pulse width (if you use the level trigger mode)
The signal delay (SD) is the delay inherent in the signal (that is, SD is
the length of time after the trigger, but before the signal of interest
occurred and becomes stable).

4. Calculate the set up time (SUT) using, SUT = 7/2.
5. Determine the gate parameters using the following equations:
м Gate delay = SUT + SD
# Gate length = r/4
Figure 3-5 shows the scheme of these parameters,
Open the “gate” during the time the signal is in a stable condition.
The time from the start time of a signal and the open time of a gate
is the “set up time” (SUT). Generally, SUT is set to half the pulse
width. This is done so that you can allow the maximum time for the
signal and RBW filter of the analyzer to become stable. You must also
consider the end of the gate. Shut the gate before the last quarter of
the pulse width to maintain a stable condition during the time the
gate is open.

Step 5: Setting RBW, VBW, and Averaging
Note uz
To Set the Resolution Bandwidth
1. Press (Bw/Avg)-
2. Set the resolution bandwidth wider than sr.
The RBW setting you can use is limited by the gate open position. You
can adjust a longer gate delay for a narrower RBW in step 5. This
is because the RBW filters need charge time until normal condition.
Therefore, you need to consider the balanced point between SUT and
RBW. Generally, the RBW filter's charge time is defined as 2/RBW.
Therefore, the SUT must be longer than 2/RBW or the RBW must be
wider than 2/SUT.
If the RBW is set narrower than 3 kHz, the analyzer turns into the
stepped FFT mode. In the stepped FFT mode, the gate length must be
longer than one FFT sampling step time. You must set the gate length
longer than the minimum gate length that is listed in Table 3-1.
Table 3-1.
Minimum Gate Length setting with RBW setting
REW Allowable Gate Length
1 Hz | >5.1857 s
3 Hz >1.6595 s
10 Hz >0.51858 s
30 Hz >0.13457 s
100 Hz >0.051213 s
300 Hz >0.012813 s
1 kHz >0.0032125 s
3 kHz >0.0016125 s
To Set the VBW
2. Set the video bandwidth.
You can set any video bandwidth (VBW) without concern for the gate
length setting. The analyzer implements the video filter using digital
processing. The video filter of the analyzer requires no settling time
for normal operation. Therefore, it is not affected by the gate length
setting.
You can also use the averaging function to reduce the variation of the
trace. The averaging function converges to the top of the variation.
This is different from the VBW, which converges to the middle of the
variation.

7. Set the number of points (NOP), by pressing (Sweep)
NUMBER: of POINTS and entering the NOP.
The allowable minimum sweep time is determined by the sampling
mode and NOP. In the normal sampling mode, the minimum sweep
time is 25 us x NOP.
Int the repetitive sampling mode, the sweep time is determined by
0.5 us x NOP. This is because that the time resolution is fixed at
0.5 ps in the repetitive sampling mode.
Notes You can set the RBW greater than 10 kHz. If you enter less than 10
kHz for the RBW, it is set to 10 kHz.
You must set the trigger source either EXTERNAL. or VIDEO “to select
the repetitive sampling mode.

To Display the Group Delay
1. Press (Format).
2. Press DELAY.
The group delay format displays phase deviation to group delay
aperture. Therefore, setting the group delay aperture affects the
trace shape. Setting a wider aperture makes the trace smoother. The
default setting of the aperture is 1% of span.
To Set the Group Delay Aperture
1. Press (Bw/Avg).
3. Enter group delay aperture value as a percentage of the span.
The Group delay aperture is based on the number of points, not the
real aperture, For example, if the number of points is 201, a 1%
group delay aperture calculates the group delay using the adjacent
measurement points on both sides. Therefore, the group delay trace
is different by the number of points setting even if the group delay
aperture is the same setting.

1. Insert a LIF or DOS formatted 3.5 inch disk into the built-in disk
drive (if you are recalling an instrument state file from the RAM
disk, skip this step).
2. Press (Save).
3. Select a save data type:
Save Data Type Press
Instrument states only STATE
Measurement data only! DATA ONLY (binary)
1 You can specify a data array type. See the “To Specify a Data Array Type”
procedure.
4. Select where the file is stored by pressing either
STOR. DEV. [DISK] (for the built-in disk drive) or
9. Enter a filename. Then press DONE.
The analyzer automatically detects the disk format as either the LIF
(Logical Interchange Format) or DOS (Disk Operating System). If you
insert an any other format type disk, an error message is displayed.
For more information, appendix C of the Function Reference provides
a complete list of the instrument state to be saved,
You can automatically recall the instrument state every time the
analyzer is turned ON. Use “AUTOREC” as a filename. The analyzer
recalls this file from a disk that is inserted in the built-in disk drive
when it is turned ON.
