[time-nuts] HP-53132A Faded and flickering display

[Timeok]

Hi all,

to avoid more display "consumption" during long acquisitions, there is 
an HPIB command to blank the display on the counter. I have asked to 
KE5FX to add this feature in Timelab during the acquisition setup. Hope 
he have time to do this.
