Amplitude Flatness Verification
This test verifies the output amplitude flatness specification at selected
frequencies. If you use a Temperature Voltage Converter (TVC) (the
recommended method)
or a wide band ACrms voltmeter (with a 50
frequencies. If you use a Temperature Voltage Converter (TVC) (the
recommended method)
or a wide band ACrms voltmeter (with a 50
Ω feed through load), perform
this procedure as described. If you are using a measurement device that
requires a transfer measurement (for example, a power meter), make the
transfer in the reference measurement at 100 kHz.
requires a transfer measurement (for example, a power meter), make the
transfer in the reference measurement at 100 kHz.
Set the function generator to the first output indicated in the table below and
make a reference measurement. Set each function generator output shown in
the table below. Measure the output of the function generator. Compare the
amplitude level measured to the reference measurement +/- the error shown
in the table. This test is a 50
make a reference measurement. Set each function generator output shown in
the table below. Measure the output of the function generator. Compare the
amplitude level measured to the reference measurement +/- the error shown
in the table. This test is a 50
Ω output termination test.
