Hi,
I own a HP8593E and have calibrated it with the use of the amplitude correction AMP COR.
WIth AMP COR on it now shows correct levels on all frequencies.
Unfortunately it seems that I have to go into the third CAL menue to activate it after each power-up.
Is there a way to have AMP COR activated by default after powering up the instrument?
The instrument is already set to memorize "LAST STATE" after power-up.
It´s only a minor but annoying "problem"...
Best regards
Andreas
Hi,
AMP COR is OFF by default because this correction is only used to compensate for a setup, for example a cable (compensation for cable loss in frequency). Even the LAST STATE configuration will not recall this correction, because it would be too easy to make level errors by forgetting to remove this correction which in fact only applies to a particular setup.
When calibrating the spectrum, this function must be turned OFF (it is automatically with the PRESET function), if you say that the levels are correct when this function is activated, then there was an error in the procedure calibration. In my case, before calibrating, I erased this memory (PURGE AMP COR) to be sure not to interfere with the procedure, and when this memory is empty, AMP COR cannot be activated.
The CORR code displayed on the left of the screen indicates that the Amplitude and Frequency corrections are activated, when there is the letter A in front (ACORR), this indicates that the AMP COR correction is applied. It is therefore an amplitude versus frequency correction in order to compensate for a specific setup.
