8.5 Performance test
8-12
FRA 51602
8.5.8 Analyzer dynamic range
This instrument : Set the oscillator AC amplitude to 10 Vpk and the sweep frequency to from
10 Hz to 2 MHz.
Set the number of integrations to 300 cycles and the analysis mode to
CH2/CH1.
Measuring instrument : (none)
Connections : Connect the BNC short plug to the
CH1
connector. Connect the
OUTPUT OSC
to
CH2
.
Measurement method : Perform upsweep measurements with the instrument, and read the
minimum gain values in the ranges from 10 Hz or more up to 1 MHz and
from 1 MHz or more to 2 MHz from the LCD screen.
After completing the measurements, change to the connections for
measuring the dynamic range of CH2 and set the analysis mode to
CH1/CH2. Perform a sweep measurement and read the minimum gain
values for each range from the LCD screen.

other such factors. However, the test will be passed if most of the data that results from the sweep
measurement does satisfy the value.
