？Q

How to determine whether the single-mode VOA optical attenuator has power monitoring?

A

You can intuitively see whether there is input power & output power on the LCD UI panel, as follows:
？Q

Does the sampling oscilloscope dca4201 second generation host computer have real-time mode display?

A

Yes, select setup instrument mode setup - in the GUI and check the tuning mode.
？Q

Can the sampling oscilloscope display the equipment temperature on the upper computer of dca4201 second generation computer?

A

Yes, select setup display, and setup check temperature display in the GUI.
？Q

How does the second generation of sampling oscilloscope dca4201 record the log log of the instructions sent by the automation software to the upper computer?

A

Select tools SCPI programming tools in the GUI and check it; The log will be saved to the log folder of the upper computer.
？Q

How to set the threshold mode of the sampling oscilloscope dca4201 second generation computer when testing mask magin?

A

Mask test setting - select Maunal mode - set the corresponding threshold.
？Q

What is the recommended light entry range of the second generation of sampling oscilloscope dca4201?

A

-About 3dB to - 6dbm.
？Q

Is there light on the oscilloscope screen of the second generation of sampling oscilloscope dca4201?

A

First, confirm whether the device under test emits light, which can be checked with a power meter; Confirm that there is light on the power meter and no light on the oscilloscope. After the equipment is restarted and connected, conduct dark current calibration and check again; If none of the above works, confirm whether there is light of more than 0dB entering the optical port and damaging the internal devices.
？Q

How does the sampling oscilloscope dca4201 display the current temperature of the device and the temperature during calibration on the GUI?

A

Measure configure measurement.
？Q

The Er of the sampling oscilloscope dca4201 is unstable or the equipment of competitive products is quite different

A

Before use, it needs to heat the engine for more than 15 minutes to make the equipment reach thermal balance, and then conduct dark current calibration. At this time, the ER brush value is stable; In addition, if there is still a gap between ER and competitive products at this time, ercf compensation can be made. The method is: measure configure measurement - set the corresponding ercf compensation.
