15.0 Connections
12.0 SMA input (measurement of external signals)
Starting with the NF-3020, an SMA input is available.
Here, you can connect arbitrary external sensors, like
large, highly sensitive coils, specialized antennas or taps
and similar devices. The incoming signal strength is then
shown in volts.
This additional input allows a wide range of additional
applications and converts SPECTRAN into a true allround
instrument. To activate the SMA input, simply press
the key 7 and select the analog sensor (the Status display
reads “ANALOG“).
The highly sensitive, ultra low-noise input of SPECTRAN (depending on model
down to 0.74nV/ Hz) has specifically been designed for measurement of extremely
weak signals, thus the maximum allowable input voltage is very small. The
maximum input voltage is 200nV to 200mV (0.2V) with a frequency of 20/30MHz
max. (in case the SPECTRAN is equipped with the 20/30MHz option).
WARNING: Be sure not to overload the input! The maximum allowable voltage
is just 200mV (0.2V). Voltages above 1V can destroy SPECTRAN’s highly sensitive
amplifier circuitry!
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.
