Setting power level with Auto Power Range set function

When the Auto Power Range set function is effective, the proper source attenuator and
power range are selected automatically, as shown by the figures below, according to the
maximum frequency and maximum output power of each channel (except for instruments
with option 213, 313, or 413).
NOTE Under the following conditions, turn OFF the Auto Power Range set function and set the
power range and power level manually, according to Setting power range manually
on page 77.

When different power ranges are selected in multiple channel measurement settings. In
this case, an error message is displayed to avoid source attenuator damage. (For
example: When Channel 1's stop frequency is 8 GHz and Channel 2's stop frequency is
2 GHz with a 0 dBm setting, the error message "Continuous switching may damage
source attenuator" is displayed because each selected power range is different.
When you cannot obtain the desirable power sweep range. (For example, if you want to
set start power to - 25 dBm and stop power to 7 dBm at 2 GHz CW, you cannot set the
start power level below - 20 dBm when Auto Power Range set function is ON.)
