Chapter 3: Testing Performance
Analog Bandwidth -- Maximum Frequency Test
34
8 Measure the input power to the scope channel and convert this measurement to Volts
RMS using the expression:
For example, if the power meter reading is 4.0 μW, then Vin = (4.0*10
-6
* 50Ω)
1/2
=
14.1 mVrms.
Record the RMS voltage in the Analog Bandwidth - Maximum Frequency Check section
of the Performance Test Record (Vin @ 50 MHz).
9 Press [Clear Display] on the scope and record the scope V rms reading in the Analog
Bandwidth - Maximum Frequency Check section of the Performance Test Record (Vout
@ 50 MHz).
10 Calculate the reference gain as follows:
Record this value in the Calculated Gain @50 MHz column in the Analog Bandwidth -
Maximum Frequency Check section of the Performance Test Record.
Notes
• For all scope readings in this procedure, use the mean value in the Measurements display area at the
bottom of the screen.
