Is there a reference on how to write/update E-Series sensor EEPROM data using the E4418/19 power meters?
I've read through the material on how the Cal Factor Blocks are structured and can decipher the frequency tables and correction values. I've located the Date, Serial Number, Tracking number, and Calibration Place - but any changes I make result in sensor EEPROM errors that I assume are related to the checksum.
I see that the N1913/14 power meters have a command (SERV:SENS:CALF) to write the Cal Factor data and update the checksum. Unfortunately, though I can read and write the EEPROM data using the E4419 power meter, I can't find any reference on the range of values in the checksum and where the checksum is stored.
Any help would be appreciated.

This issue was fixed in the N1913/4A power meters which is why you see a SCPI command to do this. Review the N1913/4A Programming Guide for information on this command and the data format. This format and SCPI command DOES NOT APPLY to the E4418/9B.
It is possible to Read and Write the cal factor information using a E4418/9B power meter using a speciall written software specifically for this purpose. You can get a copy of this software by contacting the Agilent Response Center at 1-800-829-4444. Tell them you want the E4418/9B Cal Factor Read/Write Runtime VEE software. This software is freeware and is not supported by Agilent. Be sure and read the ReadMe text before using.
