Warning:

| In order to prevent or reduce the mutual interference caused by multiple devices through the power supply, especially the peak pulse interference caused by high-power equipment which may cause the destruction of the hardware of the spread spectrum test module, it is better to use the millimeter wave spread spectrum controller to supply power to the test module.
---|---|---
|

Warning:

| Bad or wrong grounding may damage the instrument, or even cause personal injury. Make sure that the instrument ground wire is in good contact with the power supply ground wire before powering on the test module. Before the test module is electrified and turned on, verify that the supply voltage is normal.
---|---|---

4 Electrostatic Protection
Electrostatic protection is often neglected. The accumulated electrostatic discharge from the human body can easily damage the sensitive circuit elements inside the instrument, greatly reducing the reliability of the instrument. Even a small electrostatic release can cause permanent damage to the device. Therefore, electrostatic protection measures should be taken as far as possible. We usually take the following two anti-static measures:

• Combination of conductive table mat and wrist strap.
• Combination of conductive floor mat and foot wrist strap.

To use the two methods above simultaneously can provide good anti-static protection, if only one method is to be used, only the former can provide reliable protection. Good anti-static work habits can reduce the damage of components and instruments, so when using the instrument, try to meet the requirements below:

• Work in an environment with antistatic measures.
• When you are going to touch electrostatic sensitive components, accessories or to make connections, be sure to wear anti-static wrist strap.
• Ensure you are grounded before cleaning and checking electrostatic sensitive devices, instrument test ports, or making connections. This can be achieved by touching the instrument test port or the grounding housing of the test cable connector.
• Ensure that all instruments are properly grounded to prevent static accumulation.

Chapter III User Inspection

1 Starting up millimeter-wave VNA extender
To start up the spread spectrum test module, perform as follows:

• Connect the test module to the DC power supply that meets the requirements with the qualified power cord.
• Turn on the DC power switch.
• The fan of test module works normally. In order to make the instrument to meet the required performance requirements, the test module should be preheated for at least 30 minutes before measuring.

|

Warning:

| Before the test module is electrified, verify that the supply voltage is normal, so as to prevent the instrument from being damaged! When the instrument is placed in the cabinet, the air convection inside and outside the instrument must be ensured. Every 100 W of thermal power in the cabinet requires environmental temperature (outside the cabinet) to be 4 ℃ lower than the maximum temperature of the instrument. If the total thermal power in the cabinet exceeds 800W, forced ventilation must be taken!
---|---|---

2 Shutting down millimeter-wave VNA extender

• Turn off the RF local oscillator input of the test module.
• Turn off DC power supply and enter shutdown state.
• When the millimeter-wave VNA extender is shut down, unplug the power cord of the back panel of the millimeter-wave VNA extender if necessary.

Chapter IV Routine Maintenance

1 Regular cleaning of the front panel of the test module: After being used for a period of time, the front panel of the test module should be cleaned. To do this, perform the following steps:

• Shut down and unplug the power cord.
• Use clean soft cotton cloth to dip in the special detergent (no alcohol) for the instrument, and then gently wipe.
• Dry it with clean soft cotton cloth.
• When the special cleaning agent is dried, the power cord can be connected.
  |

Caution:

| Do not use cleaning agent containing fluoride, acidic or alkaline substances. Do not spray the cleaning agent directly onto the panel, otherwise it may penetrate into the machine and damage the instrument.
---|---|---

2 Connector maintenance and measurement connection:
Although the connectors for the test module ports are designed and manufactured according to the highest standards, the lifetime of all these connectors is limited. Due to the unavoidable wear and tear during normal operation, the performance index of the connector will decrease or even fail to meet the measurement requirements. Correct maintenance of the connector and measurement connection can not only obtain accurate and repeatable measurement results, but also prolong the service life of the connector and reduce the measurement cost. In the actual use process, pay attention to the following aspects:

Checking the connector:
When carrying out connector inspection, you should wear an anti-static wrist strap and use a magnifying glass to check the following items:

• Whether the electroplating surface of the connector is worn, and whether there is a deep scratch.
• Whether the connector thread is deformed.

Cleaning the connector:
When clean the connector, you should wear an anti-static wrist strap, and clean the connector as the following steps:

• Use clean low pressure air to remove loose particles in connector thread and on the joint surface. Thoroughly inspect the connector. If further cleaning is required, do as the following steps:
• Make the cotton swabs (no fuzz) wet (but not soaked) with isopropyl alcohol.
• Use cotton swabs to remove dirt and debris on the joint surface and in the threads of the connector. When cleaning the inner surface, be careful not to apply external force to the inner conductor  the center, do not leave the fiber of the swab on the central conductor of the connector.
• Let the alcohol evaporate and then use the compressed air to clean the surface.
• Check the connector, confirm there are no particles and residues.
• If the defect of the connector is still visible after cleaning, it means that the connector may have been damaged, it should not be used again. Confirm the cause of the damage of the connector before carry out measurement connection.

Connecting the connectors:
Before measurement connection, the connector should be inspected and cleaned to ensure that the connector is clean and without defects. The anti-static wrist strap should be worn when connecting. The correct connection methods and procedures are as follows:

• Align the axes of the two interconnecting devices to ensure that the axes are in a straight line, so that the plug pin of the male connector concentric may slide into the socket finger hole of the female connector. As shown in Figure 4-1: Figure 4-1 Axes of the interconnect devices in a straight line
• Move the two connectors together straightly so that they can engage smoothly. Rotate the screw sleeve of the connector (note not to rotate the connector itself) until it is tightened. There should be no relative rotation between the connectors during the connection. As shown in Figure 4-2: Figure 4-2 Connection method
• Use the torque wrench to tighten the final connection. Pay attention to that the torque wrench should not exceed the starting break point. Use an auxiliary wrench to prevent the connector from turning. As shown in Figure 4-3:Figure 4-3. Use the torque wrench to tighten the final connection
• Disconnecting the connectors:
  • Support connectors to prevent distorting, shaking or bending forces to be applied on any connector.
  • An open end wrench can be used to prevent the connector from rotating.
  • Use another wrench to loosen the screw sleeve of the connector.
  • Rotate the screw sleeve by hand to the final disconnection.
  • Pull the two connectors straightly to separate them.
• 2.5 Using the torque wrench:
  • Make sure the torque of the torque wrench is set correctly before use.
  • Make sure that the angle between the torque wrench and another wrench (used to support connectors or cables) is within 90 degrees before applying force.
  • Grab the end of the torque wrench handle gently and apply force perpendicular to the handle until the wrench breaks. As shown in Figure 4-4:
• 2.6 Using and storing the connectors:
  • Protective sheath should be applied to the connector when it is not used.
  • Do not keep various connectors, air lines, and calibration pieces in one box at random, this is one of the most common causes of connector damage.
  • eep the connector and test module at the same temperature. The temperature of the connector can be significantly changed when it is held by hand or cleaned by compressed air. It should be used for calibration when the temperature of the connector is stabilized.
  • Do not touch the joint surface of the connector. It is difficult to remove grease and dust particles from the joint surface.
  • Do not place the contact face of the connector on a hard table. Contacting with any hard surface can damage the electroplated coating and joint surface of the connector.
  • Wear an anti-static wrist strap and work on a grounded conductive table pad to protect the test module and connector from electrostatic discharge.
