Agilent N8201A Performance Downconverter Synthetic Instrument Module, 250 kHz to 26.5 GHz 389
Offset
Selects the offset pairs (upper and lower) that the menu keys affect, and displays the
memory selection menu from A to F for (where you can store up to 6 sets of values for Start
Freq, Stop Freq, Sweep Time, Res BW, Meas BW, Abs Start, Abs Stop, and so forth). Press
Offset until the letter of the desired offset (A, B, C, D, E, or F) is underlined. Only one
selection at a time is shown on this key label. Since the display can show only five results at
one time, the Results Index key allows you to scroll to the sixth result when all offsets are
active.
