outside either limit a message will appear on the screen showing
which limit has been exceeded and how many times this has
happened.
Wide Signal Measurement Range
The 50 Ohm input on the 2395A can accept signals between
+30 dBm and -110 dBm while providing protection to ±50 VDC.
Semi-Automated Measurements
The MMI on the 2395A has been designed to simplify many of the
measurements required for the evaluation of today’s sophisticated
communications systems. These include Adjacent Channel Power,
X dB Down, Occupied Bandwidth, Channel Power and Harmonic
Distortion.
Tune Function
X dB Down
Occupied Bandwidth
Channel Power
Use of this function allows an unknown signal to be quickly captured
and displayed on the screen. The 2395A will search its complete
frequency range for the highest level signal, capture it, display it in the
center of the screen with both the span and resolution bandwidths
being automatically set to the optimal state for best viewing.
Spectral Purity
The phase noise on the 2395A is specified at -90 dBc at 10 kHz offset
which allows its use for evaluating the spectral purity and noise
performance of systems and sub-systems.
Signal Demodulation
Demodulation of both AM and FM signals allows full testing on a
wide range of communications systems. The demodulated signal can
be viewed on the screen and is also available on the internal
loudspeaker and on headphones via a connector on the front panel.
The FM peak deviation and AM modulation depth can be measured
using the markers provided in the 2395A.
Information Storage
The 2395A is provided with the capability of internally storing up to
1,000 screen traces and 2,000 operational states. The spectrum
analyzer is also fitted with a USB 2.0 interface for download to bulk
storage.
Input Connector
The 2395A input connector is a Planar Crown® adapter and both type
N and PC 2.92 mm adapters are supplied. The PC 2.92 mm is
required for operation to 26.5 GHz and input specifications are meas-
ured with this adapter fitted. The type N adapter can be used for
operation up to 18 GHz or where low frequency operation in a type N
cable system demands the appropriate connector.
® Planar Crown is a trade mark of Weinschel Corporation.
Interfaces
IEEE 488-2, RS-232 and Printer (PCL5) interfaces are provided as
standard on the 2395A allowing its integration into automated test
systems and the print-out of screen displays.
The 2395A has been designed with future flexibility and expansion in
mind. The operating system and system memory has the capability to
have additional facilities incorporated.
