2. Product Identification
The SPINNER 2.4 mm sliding loads type BN 741650 (male) and type BN 741651 (female) are
marked with the following information for product identification:
BN 741650 or BN 741651 (SPINNER part number)
Ser. No: XXX (Serial number)
3. Intended Use
The intended use of the sliding loads BN 741650 and BN 741651 is to calibrate vector network
analyzers (VNAs) from 4 GHz up to 50 GHz for measurements of components with 2.4 mm
connectors.
Details and other limits are given in the data sheets “741650-BE” or “741651-BE”.
The products may only be operated within the specifications given in
the data sheets “741650-BE”or “741651-BE”.
Failure to observe could result in death or serious injury.
4. Improper Use
The products are not intended for any other purpose than indicated above.
If the sliding loads are not used as intended, safe operation of these products cannot be guaranteed.
The user is responsible for all personal injury and property damage resulting from improper use.
Reading the manual as well as adhering to all the information provided - particularly the safety
instructions - is considered mandatory to comply with the intended use.
5. Product Description and Scope of Delivery
The sliding loads are 50 Ω terminations optimized for best performance from 4 GHz up to 50 GHz.
The high-strength internal structure provides very repeatable connections. A precise resistor element
provides excellent stability and return loss.
The sliding loads BN 741650 and BN 741651 include the following items:
 Sliding load BN 741650 or BN 741651
 This manual
 Certificate of Calibration
 Product data sheet “741650-BE" or "741651-BE”
6. Data Sheet
The electrical, mechanical and environmental specifications of the sliding loads are given in the data
sheets “741650-BE” or "741651-BE".
ATTENTION Temperature changes may have an impact on electrical characteristics. Therefore,
the operating temperature is a critical performance factor. During a calibration
sequence, the temperature of the sliding load must be stable and within the
specified operating temperature range. Avoid unnecessary touching of the sliding
load during the calibration sequence; your fingers apply heat to them.
7. Use and Preventive Maintenance
The best measures for maintaining the accuracy of the sliding load include:
 careful handling with the inner conductor
 routine visual inspection
 cleaning

Data subject to change without notice│M36082│Issue B│2020-02-21

 proper gauging
 proper connecting techniques
Failure to detect and remove dirt or metallic particles on a mating plane surface can degrade
repeatability and accuracy and can damage any connector mated to it. Improper connections,
resulting from bad connection techniques, can also damage these devices.
7.1 Cleaning Connectors
A sufficient cleaning of the connectors is essential to ensure the integrity of the RF connections.
Connector interfaces, especially the outer conductor, should be kept clean and free of dirt and other
debris.
 Use only denatured alcohol as a solvent.
 Use the proper size of cotton swab. Tweezers and a small piece of
cotton can also be used.
 Only dampen the swab. Do NOT saturate it.
 Gently rotate the swab around the inner conductor being careful not to
stress or bend the pin.
 Never put lateral pressure on the connector’s inner conductor. The inner
conductor does not require cleaning.
 Verify that no extraneous material remains in the connector after
cleaning.
 Verify that the inner conductor has not been bended or damaged.
ATTENTION
 Do NOT use other cleaning fluids or solvents. Do NOT use water.
 Do NOT put cotton swabs in at an angle. Otherwise you will damage the
connectors.
 Do NOT use too large cotton swabs. Otherwise you will damage the
connectors.
 Standard cotton swabs are too large to fit in the smaller connector
types. Appropriately sized swabs can be purchased through a medical-
lab-type supply centre.

7.2 Connection and Disconnection
This chapter describes the process of achieving proper connections.
Connection
 Ground yourself and all components to prevent electrostatic discharge from the measurement
assembly.
 Hold on the protection cap body (4) and turn the coupling nut only (5) to remove the protection
cap (1) of the sliding load (2). Do not turn the protection cap body (4) or sliding load body (6).
 Perform visual inspection of test port and sliding load connector.
 Clean both connectors sufficiently.
 Loose lateral locking screw (3) at the end of the sliding load.
 Push inner conductor (7) carefully further into the sliding load until it sticks out at the connector.
 Align sliding load (2) and test port connectors carefully. The plug inner conductor has to intrude
concentrically into the bushing of the socket connector.
 Push sliding load inner conductor (7) very carefully into test port inner conductor until stop.
 Push the connectors straight together and tighten the coupling nut (5) hand-tight until the mating
plane surfaces have contact. Do not turn the sliding load body (6). Only turn the coupling nut
(5). Do not overstrain the connection.
ATTENTION Damage to the inner conductor may occur, if the body of the sliding load (6) is turned.
 Support the connectors properly. Relieve the connections from any bending torque.
 Tighten connection by means of a torque wrench to 90 Ncm ± 10 %.
Torque wrench with unalterable setting to 90 Ncm ± 10 % recommended (SPINNER part
number BN 15 41 41).
 Tighten lateral locking screw (3) at the end of the sliding load hand-tight.
Disconnection
 Support the connectors properly to relieve the connections from any bending torques and
forces.
 Unfasten the coupling nut (5) with open-end wrench. Do not turn the sliding load body(6). Only
turn the coupling nut (5).
ATTENTION Damage to the inner conductor may occur, if the body of the sliding load (6) is turned.
 Unplug the sliding load straight, avoid any bending, twisting or rocking.
ATTENTION Do not reconnect the sliding load right after disconnection without repeating the
complete connection sequence described above. Non-compliance will damage
sliding load and test port inner conductors.

8. Handling and Storage
ATTENTION Sliding loads are sensitive to impact. Do not drop!
Keep dry and avoid exposure to sudden temperature changes to prevent condensation.
Environmental conditions for storage are specified in the data sheets “741650-BE” or "741651-BE".
 Loose lateral locking screw (3) at the end of the sliding load.
 Push inner conductor (7) carefully further into the sliding load until it sticks out at the connector.
 Align sliding load (2) and protection cap (1) carefully. The plug inner conductor has to intrude
concentrically into the bushing of the socket connector.
Push sliding load inner conductor (7) very carefully into protection cap inner conductor until
stop. Hold on the protection cap body (4) and tighten the coupling nut (5) hand-tight until the
mating plane surfaces have contact. Do not turn the protection cap body (4) or sliding load body
(6). Only turn the coupling nut (5).
Do not overstrain the connection.
 Tighten lateral locking screw (3) at the end of the sliding load hand-tight.
 Store the sliding load in a box when not in use.
 Never store the sliding load without the protection cap. This is the most common cause of
damages during storage.
 Avoid touching mating plane surfaces with your fingers. Residues on the connector interface
may degrade the performance of the sliding load and can only be removed with difficulty.
 Always make sure that the connectors are in a clean condition.
 Avoid the contact of the sliding load interface surfaces with any hard material. The plating and
the mating plane surfaces may be damaged if the interface contacts any hard surface
uncontrolled.
 After any shock to the sliding load (e.g. drop down on the floor) recalibration is recommended.
9. Recalibration
The suggested initial interval for recalibration is 12 months or 500 matings, whichever comes first.
The actual need for recalibration depends on the use and the maintenance of the sliding load. The
recalibration interval should begin with the day of initial use after recalibration.
The SPINNER recalibration service includes
 cleaning of the connector interfaces
 electrical testing
