Are your
acoustic sensors working?
The
SW51 is a versatile test instrument designed to measure the input and output
levels of almost all subsea electro-acoustic devices. The PROBE can provide operators with
critical performance readiness criteria prior to deployment.
Check transponders, scanning sonars, pulse sonars, beacons, side-scan systems,
DP systems and many others where access to the transducer(s) is available.
The
SW51 will become a focal point for your preventative maintenance program and
save hours of test and evaluation time.

A
FEW OF THE SW51 FUNCTIONS
 |
Check
transmitter output at transducer. |
|
Measure
band edge limits. |
|
Measure
receive sensitivity. |
|
Check
display function. |
|
Interrogate
transponders and measure response. |
|
Check
pinger/beacon output. |
|
Observe
Doppler and AGC shift on Doppler systems. |
|
Measure
"zero beat" frequency. |
|
Pulse
rate, width, frequency, burst output
and CW.
