The Channel Standard softkey is a shortcut to load 
a factory- preset standard file (*.STD) which is 
located in system memory as default. The standard 
file list includes most communication protocol 
standards which is used in several countries.

Freq Offset
Key access: [FREQ] > {Freq Offset}
Allows you to input a frequency offset value that is 
added to the frequency readout of the marker, to 
account for frequency conversions external to the 
analyzer. Offset entries are added to all frequency 
readouts including marker, start frequency, and 
stop frequency. Offsets are not added to the span 
or frequency count readouts. Entering an offset 
does not affect the trace display.
