Fuse Type Slow Blow Type ‘T’
a) Achieved during the saw tooth waveform fall time. This is calculated by
(ma) =
(μF) (∆
)
∆
b) The output drive amplifier will current limit the load to 26 mA max. Although
the unit may operate continuously under these conditions, it is not
recommended since the unit will heat up causing stress to the electronics.
c) The rise time adjustment range for each sweep setting is as follows:
= (0.01 × Sweep Expansion Setting) to (0.1 × Sweep Expansion Setting)
d) Defined as the scaling error between 1X and any other gain settings (ex. 2X
± 0.5%).
e) Measures with SA200 series scanning head connected to output.
f) ‘Ramp’ refers to the rising, or scanning, edge of the ‘Output’ waveform.
g) The gain error does not apply when using a 50 Ω load since the user-
installed output terminator will probably have a resistance tolerance greater
than the gain errors above. Also note that the 50 W output series resistance
is 49.9 W ± 1%. This will also factor into gain error when using a 50
Ω load.
h) Test performed with a 50 Ω terminator and a 6’ (~1.8 m) 50 Ω coax cable.
