This function is only available with the HP 83480A, or if the HP 83480K
option is installed in an HP 54750A.
The Units function lets you set the instrument timebase to basic time units
or to bit period units . Bit period units provide an easy and intuitive way to
display digital communication signals . Instead of having to compute the time
interval required to display two bits or eyes , you can simply set the scale to
two bits . Refer to the Scale softkey , earlier in this chapter .

Bit rate
This function is only available with the HP 83480A, or if the HP 83480K
option is installed in an HP 54750A.
Bit rate allows the time base to be congured for a variety of standard optical
and electrical telecommunications rates . If you are measuring a signal with
one of these standard rates , the scale and position functions will coincide with
this rate .
