AWT Global introduces PIM Tester for Laboratory and QA<br />
helpful for recording measurement<br />
graphs. Every screenshot<br />
offers fields for entering special<br />
DUT or user data (for example,<br />
workstation identifier, DUT type<br />
or serial numbers) and entries<br />
can be made via a keyboard or<br />
a bar code scanner.<br />

AWT Global has launched a<br />
new line of Passive Intermodulation<br />
(PIM) Testers - the PIM<br />
S1L Series. These analyzers are<br />
well suited to meet the requirements<br />
of Laboratory and Quality<br />
Assurance applications and<br />
are offered in the 700, 850, 900,<br />
1800, 1900, 2000, 2100 and<br />
2600 MHz mobile communications<br />
bands.<br />
Other bands and customized<br />
frequency combinations are<br />
also available on request. PIM<br />
S1L features an adjustable RF<br />
signal power range of 15 dBm<br />
to 44 dBm (higher power levels<br />
are available). It has also a soft<br />
power up (SPU) function, ramping<br />
measurement power up<br />
slowly. This is a feature particularly<br />
helpful to avoid strong<br />
reflections when measuring<br />
antennas, The analyzer excels<br />
by providing a receiver sensitivity<br />
of -172 dBc, a measurement<br />
carrier accuracy of ±0.35 dB and<br />
a noise floor as low as -138 dBm<br />
(@ 300 Hz BW).In addition to<br />
third order intermodulation products,<br />
higher order IM products<br />
can also cause interference and<br />
distortion in receiving bands.<br />
The PIM S1L analyzers measure<br />
and display up to four intermodulation<br />
products simultaneously.The<br />
analyzer runs on the<br />
Windows OS, has a large 10.2”<br />
touchscreen TFT and comes<br />
standard with three (3) USB<br />
ports and one Ethernet interface<br />
for connecting to external<br />
devices and networks. Measurement<br />
results can be stored internally<br />
or externally in numerical<br />
form, as PDF reports, or as jpg<br />

Manta Ray Detects<br />
Hidden Cell Phones<br />
That Are Turned Off<br />
Berkeley Varitronics Systems,<br />
Inc. (BVS) has released Manta<br />
Ray detector in an effort to<br />
search and seize contraband<br />
and unauthorized cell phones<br />
hidden inside a variety of<br />
materials that trick common<br />
metal detectors.<br />
Manta Ray is a close-range,<br />
highly sensitive detector that<br />
specializes in identifying specific<br />
but common components<br />
found in all cell phones. This<br />
allows Manta Ray to „see“<br />
phones that are ACTIVE or<br />
INACTIVE, ON or OFF and<br />
even hidden behind walls<br />
and dense materials such as<br />
sheetrock, concrete and aluminum.<br />
This is an important<br />
distinction because most metal<br />
detectors in use today are falsely<br />
triggered by all metals<br />
while Manta Ray detects the<br />
presence of mobile phones<br />
through a variety of metals<br />
including aluminum, brass,<br />
copper and more. In the search<br />
for contraband cell phones<br />
in correctional facilities, this<br />
allows for swifter sweeps of<br />
both individuals and cells. In<br />
the case of unauthorized cell<br />
phones in both public and private<br />
facilities, Manta Ray provides<br />
a faster and much less<br />
intrusive way of searching for<br />
cell phones to enforce unauthorized<br />
cell phone use.<br />

Wireless<br />
Richardson RFPD Introduces Trio of 1 kW RF Power Amplifier Systems from Empower<br />
Richardson RFPD, Inc. announced three<br />
new 1 kW solid state broadband high<br />
power amplifier systems from Empower<br />
RF Systems, Inc. (Empower). Part<br />
of Empower‘s „Size Matters“ campaign,<br />
the devices offer unrivaled size and power<br />
advantages, are packaged in a 5U, air cooled<br />
chassis, and deliver more than 1 kW of output<br />
power from 20 to 1000 MHz. Performance<br />
is guaranteed over the full bandwidth<br />
and temperature.<br />
Built-in control, monitoring and protection<br />
functions include user interface capabilities<br />
and event logs that allow for remote<br />
management and diagnostics via an embedded<br />
web server, enabling simple network<br />
managed site status monitoring and control<br />
by connecting the units‘ Ethernet ports to a<br />
LAN. Using a web browser and the units‘<br />
IP addresses (IPV6) allows ease of access<br />
with the benefit of multilevel security. The<br />
control system cores support hardware<br />
encryption and run embedded, Linux operating<br />
systems. These 1 kW products are<br />
designed to be continuously monitored for<br />
critical performance parameters, including<br />
temperature, current consumption, and voltage<br />
levels, with protection and shutdown<br />
options available via the microcontrollers.<br />
This high level of device management<br />
combined with detailed thermal simulations<br />
and heat spreading techniques result in<br />
high reliability and ruggedness, making the<br />
devices ideally suited for high power continuous<br />
wave (CW), modulated and pulse<br />
applications.<br />
