Alan Broadband Co. now
offers a 1 MHz to 8 GHz
Wireless Field Strength
Tester, model ZC300.
This hand-held device
uses active wireless ICs
(instead of diodes) for
detection, attaining a
higher sensitivity and
bandwidth for field strength measurements. Sensitivity is - 70 dBm @ 2.4 GHz
and higher at lower frequencies.
The ZC300 has both fixed internal
antennas and coaxially connected
antennas to detect and locate RFI
sources and cable leaks, as well as
mW hidden Fox transmitters. It is
ideal for wireless installations; far
field tuning-up of transmitters and
antennas, plotting antenna fields in
dB, and measuring antenna
front/back ratios. It helps to align distant antennas and locate sources of
undesirable oscillations. The ZC300 is
complete with a directional 1. 8-6. 4
GHz Log Periodic antenna for $599.

Multilabs has announced the
is a serial LCD
graphics module with an
screen. The LCD has a resolution of 160
by 80 pixels and can display both
graphics and text. The touchscreen is
a resistive type screen such as the types
used on PDAs and the like. This allows
the ezDISPLAY to track the position of
the touchscreen down to the pixel. The
integral controller breaks down the
complex decoding operation of the
touchscreen and returns a simple X and
Y position for ease of operation.
The ezDISPLAY is controlled
through an asynchronous communication protocol that allows an external
control to draw images and retrieve
information. Both graphic and text commands are provided to allow for a wide
range of applications. Some of the serial commands that control the ezDISPLAY
are: Add Character, Character Placement,
Download Screen, Erase Area/Screen,
Get Touchscreen Data, Draw Line
(Straight), Pixel, Retrieve Screen, Save
Screen, and Touchscreen Calibration.
The ezDISPLAY comes with a complete built-in ASCII character set that is
user replaceable and a generous amount
of memory to create 32 user-defined
characters. All user-defined characters
are stored in non-volatile memory so
they are not lost when power is removed.
Memory is also provided to store up
to four screens that can be re-loaded at
any time. Again, these saved screens are
stored in non-volatile memory. Characters and graphics can be intermixed on
the screen and characters can be placed
in landscape or portrait mode along with
many other options. The ezDISPLAY is
also a true bitmap in that there
are no character cells. This
allows character placement to
occur anywhere on the screen.
The ezDISPLAY even has a
command that allows downloads of screens from other
sources such as those drawn
on a computer. Screens can be
pre-drawn on a computer,
downloaded to the ezDISPLAY, saved
in memory, and then recalled when
needed in the end-use application.
The ezDISPLAY comes with a
floating character that makes a great
companion to the touchscreen. The
floating character can be displayed and
moved around anywhere on the screen
without destroying any of the image on
the LCD. This adds another level of
character display to the ezDISPLAY.
The floating character can either be
controlled by the end-user controller
or it can be “latched” to the touchscreen so it automatically follows the
movement of the user stylus or finger.
The ezDISPLAY comes with four
mounting holes for secure placement
in any product and a four-pin SIP header is used to supply power and access
the serial data lines.
