Registration form (Print) Softkey
The registration form (print) softkey allows you to print outa
registration form to an externally connected printer.
You can complete the form and fax or mail it to Hewlett-Packard to ensure
that Hewlett-Packard can contact you when either software updates or new
product information becomes available. Anyone responsible for the
maintenance of the oscilloscope and anyone who is using the oscilloscope can
register. You can fil! out the form even if you are not the original purchaser.
You can also use this form to notify Hewlett-Packard of an address change.
You can print out a copy of the registration by simply connecting a printer to
the oscilloscope, then pressing the registration form softkey. If a printer is
not available, make a copy of the form that is at the end of this chapter.
Interpolation Softkey
When in the real-time sampling mode with the sample clock set to auto and
on time ranges faster than 20 ns/div, data is normally routed through an
interpolation filter that calculates and adds additional data points. These
additional data points fill in the time buckets between the acquired data
points. You can set the interpolation softkey to off to bypass the
interpolation filter and to view the actual nonfiltered (raw) data points for all
active channels (running or stopped). Active memories with real-time data
displayed at faster than 20 ns are also displayed as dots. Turning
interpolation to off also turns off any active measurements, and any attempt
to perform measurements is not allowed. Either select on or exit the system
menu to turn on the filter again.
You can also use the sequential capture mode in the time base menu to view
the raw data points. You can measure, store, and transfer over the bus the
raw data points acquired in the sequential capture mode.
Exit Menu Softkey
The exit menu softkey returns you to the utility menu.
