SAP5000D Differential Probe 3

2 Safety Instructions

This section contains essential information and warnings that must be adhered to while operating the

probe under the respective safety conditions. In addition to the safety precautions outlined in this

section, you must also follow recognized safety procedures.

1. Connect the probe to the oscilloscope before probing the signal.

2. Intended for indoor use only.

3. Keep the product's surface clean and dry.

4. Do not operate in damp environments.

5. Do not operate in potentially explosive atmospheres.

6. Maintenance procedures should only be performed by qualified technicians.

7. Ensure proper connection of signal wires, keeping the signal ground at the same potential as the

ground voltage. Do not connect the ground wire to high voltage sources. During testing, avoid

touching exposed contacts and components.

8. If you suspect a product malfunction, refrain from further operation. In the event of suspected

damage to the product, seek examination by qualified service personnel.

This product is intended for indoor operation only. Before using this product, please ensure that the

operating environment remains within the following parameter ranges.

Temperature: 5°C to 40°C.

Humidity: Maximum relative humidity of 80% at 30°C, linearly decreasing to 50% at 40°C.

Altitude: Up to 10,000 feet (3,048 meters).

Note: Consider direct sunlight, electric heaters, and other heat sources when evaluating

temperature.

Warning: Do not operate this product in explosive, dusty, or humid

atmospheres.

Caution: Do not exceed the specified maximum input voltage. For details,

please refer to the technical data.

2.3 Calibration

The recommended calibration interval is one year and should be performed by personnel with the

appropriate qualifications.

2.4 Cleaning

Only use a soft, damp cloth to clean the probe's surface. Do not use chemicals or corrosive

substances. Under no circumstances should moisture be allowed to infiltrate the probe. To avoid

damaging the probe, disconnect it from the oscilloscope before cleaning.

The probe case is not sealed and should never be immersed in any fluid.

2.5 Abnormalities

Use this probe only for the purpose specified by the manufacturer.

The probe may be damaged if it exhibits visible damage or experiences significant transport

pressure.

Bending the probe cable may affect the high-frequency performance of the probe.

If you suspect probe damage, disconnect it from the oscilloscope immediately.

To use the probe correctly, carefully read all instructions and labels.

Warning: Using the probe in a manner not specified by the manufacturer may

damage the probe. This probe and related accessories should not be directly

connected to the human body or used for patient monitoring.

3 First Steps

3.1 Delivery Checklist

First, check that all items listed on the packing list have been delivered. If you note any omissions or

damage, please contact your nearest SIGLENT customer service center or distributor as soon as

possible. If you fail to contact us immediately in case of omission or damage, we will not be

responsible for replacement.

3.2 Functional Check

To perform a function check, you will need an oscilloscope with SAPBus interface support. Follow

these steps to check the probe's function:

1. Power on the oscilloscope and allow it to warm up for 20 minutes.

2. Connect the active probe to Channel 1 of the oscilloscope.

3. Open the parameter panel for Channel 1 and inspect the probe information, including the probe

model, serial number, bandwidth, impedance, capacitance, and attenuation ratio.

4. Set the vertical scale for Channel 1 to 1V/div.

5. Set the offset voltage for Channel 1 to 0V.

6. Measure the average voltage for Channel 1. The reading should be within ±(1.5% * full-scale

reading + 10mV). If the reading is outside this range, the check does not pass.

7. Change the vertical scale for Channel 1 to 500mV/div, 200mV/div, 100mV/div, 50mV/div,

20mV/div, and 10mV/div, respectively. Repeat step 6 for each scale to check the average

voltage readings at each scale level.

3.3 Quality Assurance

The probe is covered by a 1-year warranty from the date of shipment, provided it is used and

operated under normal conditions. SIGLENT can repair or choose to replace any product returned to

an authorized service center during the warranty period. We must first examine the product to make

sure that the defect is caused by the process or material, not by abuse, negligence, accident,

abnormal conditions, or operation.

SIGLENT shall not be responsible for any defect, damage, or failure caused by any of the following:

1. Repairs or installation conducted by individuals not authorized by SIGLENT.

2. Connection of incompatible devices and improper connections.

3. Any damage or failure resulting from the use of products provided by non-SIGLENT suppliers.

3.4 Maintenance Agreement

We offer various services through maintenance agreements. We offer extended warranties, and you

can create a maintenance cost budget after the one-year warranty period. We offer installation,

training, enhancements, on-site repairs, and other services through dedicated supplementary

support agreements. For more information, please contact the SIGLENT customer service center or

your national distributor.

4 Probe Technical Specifications

SAP5000D is a high-bandwidth differential active probe known for its features such as high

bandwidth, low noise, and high input impedance, making it suitable for measuring high-speed signals.

Its high input resistance and low input capacitance characteristics ensure minimal load introduced to

the measurement system.

The SAP5000D active probe utilizes the SAPBus interface and is compatible with oscilloscopes that

support the SAPBus interface, such as the SDS5000X, SDS6000 Pro, and SDS7000A series

oscilloscopes. The SAP series active probes do not require external power sources as the

oscilloscope provides power and communication interface to the active probe through the SAPBus.

When connected to the oscilloscope, the SAP series active probes allow you to read probe

information from the oscilloscope's interface.

Here are the performance characteristics:

Probe Bandwidth: DC to >5GHz

Single-ended input resistance: 10kΩ

Differential input resistance: 20kΩ

Probe gain: ÷10

Differential input capacitance: 400 fF

±2.5V input dynamic range

±12V offset voltage setting range

SAPBus interface

4.1 Model and Specifications

The specifications of the probe need to meet the following conditions:

1. The probe is within its valid calibration period.

2. The environmental temperature is within 25°C ±5°C.

3. The probe is correctly connected to the oscilloscope.

4. The probe and oscilloscope are in a thermally stable environment, and both the probe and

oscilloscope have been preheated for at least 20 minutes.
