SPECTRAN offers the possibility to choose between several different physical
units. You can select between various units for magnetic fields at any time in the
“Unit“ menu.
Possible choices are:
T
,
G
and
A/m
.
Measuring field strength [V/m; A/m; T; G]
When using
an antenna or sensor
instead of direct signal input to make mea-
surements, yo mostly wish to measure field strength (instead of voltage or out-
put).
SPECTRAN allows measurement of electric fields in V/m.
Magnetic fields can be measured in G (Gauss), T (Tesla) or A/m
(Amperes/meter).
As the readout can quickly turn into a gigantic row of digits when measuring field
strengths, SPECTRAN offers a very practical
autorange feature
: instead of an
endless row of digits, it simply adds a corresponding prefix to the readout, such
as
p
,
n
,
µ
or
m
(for example:
m
T).
Measuring voltage [V]
When using direct signal input via the SMA connector, you can directly measu-
re the applied signal in Volts [V]. Input voltage can range from approx.
200nV
to
200mV
. The extremely high sensitivity of only 200nV allows measurement of
even the weakest signals.
You can expand the measuerement range with our optional Differential
Probe up to 240V! The probe also protects the input from to high voltage
(up to 1500V). The probe is a “must have” if you want to measure DSL lines
etc.
