- Analog voltage output: 5.0 kHz to 300 Hz bandwidth
With the N7747A and N7748A, the highest optical performance is now
offered in the N77 platform for compact automated instrumentation.
The high optical performance encompasses the highest sensitivity
available with -110dBm and correspondingly low noise and high
stability to accurately measure and monitor weak signals and small
signal changes. This is supported by high relative power accuracy
with low polarization dependence and low spectral ripple. These
instruments combine the proven optical performance of the 81634B
sensor modules with small footprint of the N77 series platform that
offers 100X more memory per channel and faster data transfer rates
with continuous logging functionality. The ability to upload
buffered data while logging new data permits continuous long-term
monitoring of weak signals and small signal changes. Up to eight
high-sensitivity optical power meters now fit in a single rack
unit. Optical connections are made with the interchangeable 81000xI
connector interface system.
Twice the ports in half the rack space. These instruments enhance
the proven optical performance of the 81634B sensor modules with
the large memory, fast data transfer and small footprint of the N77
series platform. Eight high-sensitivity optical power meters now it
in a single rack unit. Optical connections are made with the
interchangeable 81000xI connector interface system so the
instrument can be easily adapted to different iber connector types.
Each optical port has 2 buffers of memory, each able to log up to
1M samples. With the ability to upload one buffer while the other
is recording measurements, this permits continuous monitoring over
extended times with sensitivity to small transients. Details for
programming this logging are given in the application note
5990-3710. The functionality is the same used in the N7744A and
N7745A except that the high-sensitivity models use lower bandwidth
to match the low-noise performance. This includes lexible choice of
averaging times to optimize sampling at any rate.
The N7747A and N7748A also include an analog output for each
optical channel. This provides a 0 to 2 V signal proportional to
the optical power, scaled by the selected power range and allows
analog monitoring of signals with up to 5 kHz bandwidth. The
instruments have USB, LAN and GPIB interfaces for control with the
SCPI command set also used for the 816x, N7744A and N7745A optical
power meters. The updated versions of the N77xx Viewer user
interface program and the 816x VXI Plug&Play driver can be
used, also with the N7700A IL engine to measure the high dynamic
range in optical ilters.
