hi all,
my initial asssumption is yes:
is the Agilent spectrum analyzer still receiving power even it is turn off?
that's means if there is high power surge even if it turned off, the unit might get damage.
thanks if anyone can clarify.

Most of our newer spectrum analyzers do not have an “off” setting; they have a standby setting. This means that while the analyzer is not operational, it is still consuming a small amount of power. In some analyzers, this standby power also powers a 10 MHz reference, to keep it stable. This is not done in the X-Series or ESA family of analyzers, however.
Instead, the small amount of power consumed during standby is used solely to detect when the power switch is pushed and to power a real-time clock (although the real time clock also has a battery backup).
Since the analyzer is drawing very little current in the standby mode, it will probably not be susceptible to a high power surge (remember, power is voltage times current). However, it might be susceptible to a high voltage transient.
To date, I am not aware of any instances where we believe an analyzer was damaged by a voltage transient or power surge while in standby.
