Safety-2 PN: 10580-00171 Revision A MP1026A MM
For Safety
Warning Always refer to the operation manual when working near locations at which
the alert mark, shown on the left, is attached. If the operation, etc., is
performed without heeding the advice in the operation manual, there is a
risk of personal injury. In addition, the equipment performance may be
reduced.
Moreover, this alert mark is sometimes used with other marks and
descriptions indicating other dangers.
Warning
When supplying power to this equipment, connect the accessory 3-pin
power cord to a 3-pin grounded power outlet. If a grounded 3-pin outlet is
not available, use a conversion adapter and ground the green wire, or
connect the frame ground on the rear panel of the equipment to ground. If
power is supplied without grounding the equipment, there is a risk of
receiving a severe or fatal electric shock.
Warning This equipment can not be repaired by the operator. Do not attempt to
remove the equipment covers or to disassemble internal components.
Only qualified service technicians with a knowledge of electrical fire and
shock hazards should service this equipment. There are high-voltage parts
in this equipment presenting a risk of severe injury or fatal electric shock to
untrained personnel. In addition, there is a risk of damage to precision
components.
Warning
Use two or more people to lift and move this equipment, or use an
equipment cart. There is a risk of back injury if this equipment is lifted by
one person.
Caution
Electrostatic Discharge (ESD) can damage the highly sensitive circuits in
the instrument. ESD is most likely to occur as test devices are being
connected to, or disconnected from, the instrument’s front and rear panel
ports and connectors. You can protect the instrument and test devices by
wearing a static-discharge wristband. Alternatively, you can ground
yourself to discharge any static charge by touching the outer chassis of the
grounded instrument before touching the instrument’s front and rear panel
ports and connectors. Avoid touching the test port center conductors
unless you are properly grounded and have eliminated the possibility of
static discharge.
Repair of damage that is found to be caused by electrostatic discharge is
not covered under warranty.

6. Press the Time soft key and set the Clock Rate to 10 GHz.
7. Press the Amplitude soft key. Set the CH1 Scale to 30 mV and set Offset to 0 mV. A steep pulse rise and
fall trace should appear as shown in Figure 3-3.
8. Press the Measurement soft key and select Histogram.
9. Set the histogram window as follows:
Y1 to 5 mV
Y2 to –5 mV
Axis to Time
10. Set X1 and X2 so that the histogram window is over the rising edge of the steep data signal and slightly
wider than the data. The histogram window should encompass the width of the rising edge data. Refer to
Figure 3-3.
11. Set Y1 to 2 mV and Y2 to –2 mV.
12. Press the Setup soft key and then select Clear Display to refresh the display.
13. After Hits (bottom of the measurement results area) count passes 10,000, observe std Dev data, which is
equivalent to the RMS Jitter. Record the value in Appendix A, Test Records.
3-5 Clock Recovery (CRU) RMS Jitter Verification (Option 2)
1. Set the clock output of the Pulse Pattern Generator (PPG) to 10.0 GHz, 500 mVpp.
2. Set the PPG data output to a symmetrical pattern (010101) by the following key presses:
a. Press the key under PRBS Mark Ratio so that the ½ LED is on.
b. In the Pattern section, press the left arrow key so that the LED under DATA is on.
c. In the Data Length section press the up arrow so that 6 is flashing
d. Press the 2, 4, and 6 buttons so the 2, 4, and 6 LEDs are on.
e. Adjust the Amplitude of the Data to 500 mV p-p, offset 0 mV.
f. In the Offset section, set the Offset to VOH.
g. In the Output section, turn the Output on.

3. Connect the PPG clock output to the ≥1 GHz CLK IN connector of the MP1026A.
4. Connect the PPG Data signal to the CRU IN connector.
5. Connect an RF cable between CRU OUT connector and CH2 Input connector.
6. Restore the MP1026A to factory settings by pressing the Shift key and then the Preset key, then press
the Preset soft key.
7. Press the Setup soft key and set the MP1026A as follows:
Display Mode to Eye
Channel 1 to Off
Clock Recovery to >9.8
Sampling and Accumulation to Infinite Accumulation
8. Press the Time soft key and set the Clock Rate to 10 GHz.
9. Press the Amplitude soft key, set the CH2 Scale to 30 mV and Offset to 0 mV. A steep pulse rise and fall
signal should appear.
10. Press the Measurement soft key, set Active Channel to CH2 and then select Histogram.
11. Set the histogram window as follows:
Set Y1 to 5 mV
Set Y2 to –5 mV
Set Axis to Time
12. Set X1 and X2 to set the window over the rising edge of the steep data signal, and slightly wider than the
data, see Figure 3-3.
13. Press the Setup soft key and select Clear Display soft key to refresh the display.
14. After Hits (bottom of the measurement results area) count passes 10,000, observe std Dev data. Record the
value in Appendix A, Test Records.
15. Using the RMS Jitter data from Section 3-4, step 13 and the std Dev data from the previous step,
calculate the CRU RMS Jitter using the following formula:
16. Record the CRU RMS Jitter in Appendix A, Test Records.
CRU RMS Jitter = std Dev2– RMS Jitter2

Chapter 4 — Battery Information
The following information relates to the care and handling of the Anritsu 633-44 battery pack and Lithium-Ion
batteries in general.
•The 633-44 battery pack supplied with the MP1026A may need charging before use. Before using the
MP1026A, the internal battery may be charged either in the MP1026A, using either the AC-DC
Adapter (40-168) or the 12-Volt DC adapter (806-141), or separately in the optional Dual Battery
Charger (2000-1374).
•Use only Anritsu approved battery packs. Some non-approved battery packs will fit into the MP1026A
but they are electrically incompatible and will not charge correctly.
•Recharge the battery only in the MP1026A or in an Anritsu approved charger.
•When the MP1026A or the charger is not in use, disconnect it from the power source.
•Do not charge batteries for longer than 24 hours; overcharging may shorten battery life.
•If left unused a fully charged battery will discharge itself over time.
•Temperature extremes affect the ability of the battery to charge, allow the battery to cool down or warm
up as necessary before use or charging.
•Discharge the battery from time to time to improve battery performance and battery life.
•The battery can be charged and discharged hundreds of times, but it will eventually wear out.
•The battery may need to be replaced when the operating time between charging becomes noticeably
shorter than normal.
•Never use a damaged or worn out charger or battery.
•Storing the battery in extreme hot or cold places will reduce the capacity and lifetime of the battery.
•Never short-circuit the battery terminals.
•Do not drop, mutilate or attempt to disassemble the battery.
•Do not dispose of batteries in a fire!
•Batteries must be recycled or disposed of properly. Do not place batteries in household garbage.
•Always use the battery for its intended purpose only.
4-1 RTC Battery Information
The date and time are saved using a +3V coin-style battery mounted on the main PCB. This battery has a finite
lifespan. When sufficiently discharged, the boot-up self-test will fail. Refer to Chapter 5 for the location of the
RTC battery and replacement instructions.

4-2 Battery Pack Removal and Replacement
This section provides instructions for the removal and replacement of the MP1026A battery pack.
Many of the procedures in this section are generic, and apply to many similar instruments. Photos and
illustrations used are representative and may show instruments other than the MP1026A.
1. With the MP1026A laying flat, face up, locate the battery access door, as illustrated in Figure 4-1.
2. Place a finger in the battery access door notch and push the door down towards the bottom of the
instrument, as illustrated in Figure 4-2.
3. Remove the battery access door, as illustrated in Figure 4-3.
