4.7 “TWINtest” mode
In “TWINtest” mode, you can make simultaneous
attenuation measurements at the 850 nm and
1300 nm wavelengths with the OLS-5 source or
at the 1310 nm and 1550 nm wavelengths with
the OLS-15 source. Both sources alternate
between the specified wavelengths at 4 second
intervals.
TWINtest works as follows
(The instructions below assume you are using the
OLP-5 and OLS-5 from Wandel & Goltermann.
The procedure is analogous with the other
devices named above.)
1. Reference measurement
Requirements:
✓ Connect the OLP-5 to the OLS-5 via an
optical cable, e.g. K 30xx.
✓ Both devices must be powered up and ready
to go.
✓ The OLS-5 should be in
dUAL mode.
✓ With a device from series F onwards:
Automatic wavelength detection must be
activated (“AU” indicator in the modulation
field).
✓ The values measured at 850 nm and 1300 nm
are displayed in alternation at 4 s intervals.
⇒ Hold down the “dBm/dB” key until a level of
0.00 dB is displayed in alternation at 850 nm
and 1300 nm.
REF flashes briefly to confirm
that the reference level was saved at 850 nm
and 1300 nm.
