Willtek 9102Handheld Spectrum Analyzer (100 kHz to 4 GHz) |
Portable Spectrum Analyzer Designed for Scalar Network and Spectrum Analysis |
|
Willtek’s 9102 Handheld Spectrum Analyzer is a
multifunction instrument designed for lab and field applications
concerning scalar network and spectrum analysis, including cable and
antenna measurements and EMC pre-qualification tests. The basic 9102
has a frequency range of 100 kHz to 4 GHz and a resolution bandwidth
(RBW) of an exceptional 1 kHz. An optional frequency extension allows
measurements up to 7.5 GHz. The 9102 is small in size and weight, with
a large, bright display and easy-to-use menu structure.
Options Provide Specific Solutions and Applications
The
9102 offers a vast range of options developed for specific
applications. For example, a tracking generator option supporting cable
measurements, and a reflection measurement option are available. The
flexibility these options provide ensures that the 9102 is an
affordable solution, not one that includes unneeded, more expensive
features. |

Applications
Fault finding on PCBs with the 1207 Inductive Probe
The Willtek 1207 Inductive Probe is designed for the
repair of modern, highly integrated printed circuit boards such as
those found in today’s mobile phones. High level service centres need
to measure the LO frequencies emitted on transceiver components, but do
not have test pins available for this task. Most of the latest designs
no longer have any contact point for measuring the important
synthesizers. The probe helps to overcome this obstacle by measuring
the magnetic component of the field emitted by the device under test –
a faster, more efficient way for the service technician.
R&D engineers will use the 1207 to test printed
circuits, or to perform fast EMC measurements without having to lease
an expensive shield room.
Reflection Measurements
The 9130 VSWR/DTF Reflection Measurement Option and the
9160 VSWR/DTF Bridge enable the acceptance and maintenance of
professional antenna systems, such as those used for cellular base
stations. Every customer operating a fixed or mobile radio with an
antenna system can now test the performance and match of his antenna
system over the desired frequency range in one view, using the new
reflection measurement mode. Designed for cable tests, the new DTF
measurement mode shows all relevant problems such as kinks, faulty
connectors or water ingress, which can arise along coaxial cables.
The reflection measurement mode, which is part of the
9130 VSWR/DTF Reflection Measurement Option, includes high-precision
vector calibration. So the 9102 supports you in measuring the return
loss at an accuracy that exceeds cellular phone operators’ requirements
today. Modern antenna systems for cellular networks are easily tested
with the 9130 VSWR/DTF Reflection Measurement Option and the 9160
VSWR/DTF Bridge, supporting the specified measurements with superior
performance over the full frequency range.
With its measurement precision and speed as well as its
easy handling, the 9102 with the VSWR/DTF options helps to speed up
usual antenna tests and to minimise the risk of wrong operation by
workers on site. Measurement results stored in the instrument can then
be included in your acceptance documentation, thanks to the 9100 Data
Exchange Software.
Radiation Measurements
The
9102 with the 9131 EMF Measurement Option allows network operators and
installers of broadcast transmitters to easily measure the
electromagnetic field (EMF) caused by the radio frequency emission from
the antenna. Appropriate antennas for different purposes are also on
offer and optimised for use with the 9102:
- 9172 Directional Antenna, 80 – 1000 MHz
- 9173 Directional Antenna, 300 – 3000 MHz
Regulatory
bodies and engineering offices can also check the immission of
electromagnetic radiation in the range from 100 kHz to 4 GHz, without
the need for an external PC. At the price of an instrument that only
performs radiation measurements, the 9102 also supports various other
applications in the areas of spectrum and network analysis.
Where
necessary, the 9102 can be controlled from a remote station via serial
interface or even TCP/IP. This makes it the ideal choice for cyclic
measurements over a modem or the Internet.
