Hi, all.

Suppose I have different kinds of spectrum analyzers, say S1, S2, S3...

Each spectrum analyzer has a set of settings, such as

S1(RBW1, sweeptime1, ...), S2(RBW2, sweeptime2, ...), S3(RBW3, sweeptime3, ...)

Then, I got measurement results by these spectrum analyzers, e.g.,

S1(RBW1, sweeptime1, ...) -> P1 dBm

S2(RBW2, sweeptime2, ...) -> P2 dBm

S3(RBW3, sweeptime3, ...) -> P3 dBm

All parameters maybe different, such as RBW1 != RBW2 != RBW3, also sweeptime1 != sweeptime2 != sweeptime3.

My question is:

1.

How to compare the measured powers by these different spectrum analyzers?

Namely, I want to make P1 , P2 and P3 to be comparable.

2.

Is there any way to translate P2 (which has the RBW2 and sweeptime2) to the value which meets the requirements of RBW1 and sweeptime1?

Namely, as for S2, while giving RBW2 and sweeptime2, it shows the power of P2 dBm; while setting RBW1 and sweeptime1 to the S2, what's the new value of P2?

Thanks.
