Will the MA4001A calibrator work with ML2438A power meters?

No, this calibrator does not work with the ML24xxx power meters.

Can the MA2444D power sensor accurately measure a CW signal only above -20dBm? My concern is that if I am measuring power above -20dBm with multiple carriers that the measurements will not be accurate. If this is so, do I need to pad the input to keep the signals below -20dBm?

The sensors must be in square law to get an accurate measurement. The exception would be if the carrier frequencies are very close to each other. Note: This sensor has a 3dB pad built in so up to -17dBm would be OK. Anything stronger than -17dBm and you would need an attenuator to stay in the square law region to keep your measurements accurate when in a multiple carrier environment.

My ML2438A power meter screen is flashing on and off with a green background and no data is seen on the screen.

This unit likely is in need of repair. Please contact your local Anritsu Service Center.

Is it possible to get an Ethernet or USB port on my Peak Power meter (ML248x)?

At this moment in time, ML2480A-16 (Ethernet and USB) is not a supported feature on the ML2480A Series. Units that have been, and are currently being, shipped do not have the necessary hardware or software.

Where can I find information on how to erase my product's memory?

Please contact your Sales Representative or Technical Support at 1-800-ANRITSU (1-800-267-4878) for memory erasure /letter of volatility information.
