ESG-B Firmware Installation For Versions <B.03.20
Helpful Notes for Using this Procedure
— When you are prompted with, “Turn ON the instrument NOW”, you must respond within 5
seconds to avoid a synchronization problem.
— When you are instructed to press Return, this refers to the PC keyboard Enter key, not the
Return key on the signal generator.
— When you are prompted with a Yes/No question, press the computer keyboard Y or N key and
then the Return key. This is not case sensitive.
— Once the download starts, it will take 30-60 minutes to finish. No further interaction is required.
While the download is in process, the DOS window will show the communication that is taking
place with the signal generator. Several (non-highlighted) prompts will appear on the display.
These will be automatically answered by the download program.
— When you are prompted with, “Be sure the instrument RS-232 settings under the front panel
keys [Utility] [HP-IB/RS-232] are set as follows...”, turn the signal generator on and verify the
RS-232 settings as shown, then turn the signal generator off.
— When you are prompted with, “Do you have Option UND, UN5, and/or H97? [(Y/N) Return]”
answering Yes will download the ESG firmware and Option UND, UN5, and/or H97 firmware.
Answering No, will download the ESG firmware only.
— If the signal generator is in the wrong mode, (e.g. bootrom mode) the download program will not
detect this condition. If this occurs, close the DOS window and repeat from step 7.
— If the procedure fails, due to loss of synchronization, accidental loss of power, etc., repeat the
installation procedure, starting with step 7.
— After the firmware download is complete, the signal generator will automatically reboot.
— To verify the new firmware has been downloaded into the signal generator, press
