Manual Optoelectronics APS105

De APS105 active Preselector is een narrow bandpass filter dat manueel, automatisch of op afstand getuned kan worden tussen 10MHz en 1 GHz.
De APS105 bevat een 4MHz bandpass filter welke gekoppeld kan worden met meerdere scanners of nearfield receivers.
Frequentietellers en nearfield receivers hebben een signaal nodig dat ten minste 10 tot 15 dB sterker is dan de background RF.
De APS105 versmalt de bandbreedte van 2-3GHz naar 4MHz.
De reductie van de background RF zorgt ervoor dat het gewenste signaal makkelijker op te pikken is.
Operating Modes
Manual Mode
Use shaft encoder knob to adjust center frequency.
30 detente per complete revolution of the knob.
Push in to select between 1, 10, en 50MHz per detente.
Automatic Sweep Mode
Use Sweep button to start and stop.
Sweep rate: 1, 10, 50MHZ per second.
Minimum full range sweep period: 20 seconds.
Maximum, full range sweep period: 17 minutes.
Power
Press the Power button once quickly and firmly to turn on the APS105.
Upon power up the display will default to the Center Frequency Display. for example:
CtrFreq 400 Mhz
*Locked*
Turn the unit off in the same manner. Automatic sweeping must first be stopped in order to rurn the unit off.
Press and hold the POWER button for two seconds to activate the EL backlight.
Mode Button
Press the Mode button to select between the 5 menus:
Pgm CENTER FREQ
Pgm SWEEP START
Pgm SWEEP STOP
Pgm SWEEP TIME
After 5 seconds of inactivity will default back to the CtrFreq menu.
Setup Button
Press the Setup button to enter each menu and change values.
After 5 seconds of inactivity will default back to CtrFreq menu.
Sweep Button
Press the Sweep button to start or stop automatic sweeping.
Push/Tune knob
Press and turn the KNOB to change values for manual or automatic sweeping.
Manual Tune
Manual Tune is achieved by manually moving the knob into the desired center frequency range.
Because the filter is 4MHz wide, the APS can actually see frequencies 2 MHz on each side of the center frequency. For example: if the center display read 450MHz the APS105 could pass a signal from 448MHZ to 452MHz.
Each time the knob was moved up or down the 4MHz filter would follow that center frequency.
The APS105 may be manually tuned in 1, 10, and 50MHz steps. It is recommed when first using the APS105 to tune to a known transmitting frequency using maual tune. This will allow you to become familiar in how to use the manual turn mode. Turning to fast may not allow the device being used with the APS105 enough time to determine whethet there was an actual signal present.
Automatic Sweep
Automatic Sweep is achieved by programming a start frequency and a stop frequency selecting a sweep rate of 1, 10, or 50MHz per second.
Automatic sweep is usefull for sweeping desired range to quickly determine the activity of that range.
Sweeping in 50MHz per second will allow the APS105 to sweep the entire frequency range in just seconds.
This may be useful in finding cosistently strong signals quickly.
However, it is not recommended to use this sweep rate when looking for weaker and inconsistent signals, or when sweeping in a narrow frequency range.
Sweeping in 10MHz per second allows the APS105 to sweep its entire range in under 2 minutes.
This is better for sweeping broad frequency ranges. Sweeping in 1MHz per second allows the APS105 to sweep its entire range in about 17 minutes.
This is good for sweeping narrow frequency ranges.
It is recommended to experiment with this form of sweeping first. For example: try to tune a known transmitting frequency using the three different sweep rates. Also, try altering the programmed frequency range from narrow to broad while using different sweep rates. Using the fastest sweep rate in a narrow programmed frequency range is not recommended for optimum results.
It is recommended that the sweep time be more relative to the programmed frequency range.
For examle: sweeping at a rate of 50MHz per second in a programmed frequency range of 50MHz or less may be too fast for the connected device to detect a signal even though a signal has passed through the filter.
Sweeping at a rate of 50MHz per second may be better if tuning across a broad frequency range of 200MHz or more. Also sweeping at a rate of 1MHz per second over a frequency rate of 100MHz or more may be to slow to lock onto a signal that is transmitting at different intervals.
Sweeping at a rate of 1MHz per second may be better if tuning across a narrow frequency range of 50MHz or less.
Sweeping is excelent for unattended operation where near field signals over an extended time are recorded.
In Sweep mode with a Scout for instance, all near field signals can be recorded for hours on end if both devices are supplied with external power.
Pgm SWEEP START
Use this mode when performing an Automatic Sweep. Upon entering this mode the current sweep start frequency will be displayed at the top of the display. Press the MODE button twice. Press the SETUP button once to enter the chanche SWEEP START menu.
Chanche the frequency using the knob. Press the knob down to move the cursor below the the value to be chanched, selecting between 10 or 50MHz. Rotate the knob to chanche frequency. After 5 seconds of inactivity the display will default back to CtrFrq menu.
Pgm SWEEP STOP
Upon entering this mode the current sweep stop frequency will be displayed at the top of the display.
Press the MODe button 3 times. Press the SETUP button once to enter the chanche SWEEP menu.
Chanche the frequency using the knob. Press the knob down to move the cursor below the value to be chanched, selecting between 1, 10 and 50MHz. Rotate the knob to chanche frequency , 5 seconds of inactivity the display will default back to the CtrFreq menu.
Pgm SWEEP TIME
Upon entering this mode the current sweep time will be displayed at the top of the display.
Press the MODE button 4 times. Press the SETUP button once to enter the chanche SWEEP TIME menu.
Press the MODE button to select between 1, 10 and 50MHz per second. After you have selected the desired Sweep time, lock it in by pressing the SETUP button once.
To indicate that the sweep time has been locked in, an * will appear before and after the sweep time.
For example:  *  1MHz/sec   *   After 5 seconds of inactivity the display will default back to the CtrFreq menu.
Automatic Sweep
To start an automatic sweep press the SWEEP button. The APS105 will display the start and stop frequencies as well the flashing word SWEEPING
For example;                         100-->400
**      SWEEPING       **
To stop an automatic sweep press the SWEEP button.
BACKLIGHT
To activate the backlight press and hold the POWER button for 2 seconds.
The backlight will remain on until turned off.
To turn the backlight off press and hold the POWER button for 2 seconds.

OPTOELECTRONICS Xplorer
Nearfield Receiver
Latest model
The Xplorer sweeps the range of 30MHz to 2GHz in less than 1 second, automatically locking on any active FM analog frequency in the nearfield and demodulating the audio. The two-line LCD displays the frequency of the transmitted signal on one line. On the second line the display may be changed to indicate either decoding of any sub audible tones or codes (CTCSS, DCS, LTR or DTMF) or Signal Strength.
With its amazingly quick measurement speed, the Xplorer is the most sensitive nearfield instrument of its kind. Lock onto normal two way communications from up to 1/4 mile away.
Operation allows for manual VFO tuning, manual skip, frequency lock out, auto or manual hold, and recording of 500 frequencies to memory. The memory register can also include such information as frequency, time, date, signal strength, CTCSS, DCS, LTR, and DTMF.
The Xplorer Frequency Blocks feature allows you to program up to 10 separate frequency ranges. Once programmed, you may choose to either INCLUDE or EXCLUDE each particular block. EXCLUDE is ideal for eliminating strong signals such as FM radio stations, TV stations and Paging towers. You may also want the Xplorer to only lock onto signals in a particular range, thus setting it for INCLUDE on a programmed frequency range.

UNLOCK US VERSION OPTOELECTRONICS XPLORER
Earlier versions of the Xplorer were capable of being “unlocked” to provide full 800 MHz reception by sending the string “FE FE B0 E0 7F D6 78 19 52 27 96 34 45 88 01 FD” to the unit via a terminal program. This has become increasingly important as of late as current hobbyist-grade receivers don't cover this range, and old analog cell phones placed in test mode are seeing increasing use as surveillance devices. Many older Xplorers that are often available on the used market have been previously unblocked. According to old Internet posts you can tell by turning the unit on and checking the display as it powers up. Unblocked units will show “*Xplorer*” while blocked ones will show “Xplorer”.
