Introduction
Specifications and Regulatory Information
The average is calculated on power values in Watts over
modulation frequency.
Measurement: over
frequency
sections of 1/10 of the
specified system bandwidth.
Maximum LCA electrical in power The maximum LCA
electrical in power depends on the maximum compression
that the user can accept. Here the maximum LCA electrical
in power is defined as the maximum leveled electrical out
power of the network analyzer (see user's guide of the
network analyzer).
Maximum linear operating input power (of LCA optical in) The
maximum average optical input power P
at LCA in where
max
the small signal responsivity of the optical test set receiver,
expressed in dB(A/W), degrades by less than the specified
"compression point" value. Small signal means a modulation
depth much smaller than 1.
Conditions: valid at LCA optical out wavelengths.
Measurement: modulation depth 10%.
Maximum modulated optical power (of LCA optical out) The
Modulated optical power
from LCA optical out with
maximum NWA electrical output power.
Maximum safe input power (of LCA optical in) Maximum optical
power that can be applied to the LCA optical in without
permanent change of the LCA's characteristics.
Caution: Applying more than the specified maximum safe
input power may damage the LCA!
Minimum measurable responsivity The average of the
Responsivity
measured by the LCA on a DUT with zero
output, expressed in
Decibel (dBm, dBo,
dBe). The average is
calculated over modulation frequency and from values in
linear space (rather than decibel space).
Responsivity values are converted from
Decibel (dBm, dBo, dBe)
values to linear values by:
decibel/10
linear = 10
.
The average (result) is converted back to decibels by:
decibel = 10*log
(linear)
