1-2 TAKE CARE OF YOUR RECEIVER
There are no internal operator adjustments needed. In the unlikely event of service being required, please
contact us for technical assistance.
Do not use or leave the receiver in direct sunlight. It is best to avoid locations where excessive heat,
humidity, dust and vibrations are present. Always keep the AR5001D free from dust and moisture. Use a
soft, dry cloth to gently wipe the external surfaces clean; never use abrasive cleaners or organic solvents
which may damage certain parts.
Treat the AR5001D with care; avoid spilling or leaking liquids into the receiver and the associated
power supply. Special care should be taken to avoid liquids from entering the area around the controls and
through the speaker grill or via the connection jacks.
The AR5001D is designed to operate from a good quality regulated DC power supply of 10.7 to
16.0 V, which should be capable of supplying 2 amps. Never connect the AR5001D directly to an
AC power outlet.
The polarity of the DC input jack is clearly marked; the chassis of the receiver is at negative ground.
AFETY NOTICE – Always disconnect the power supply from the AC outlet or switch off
the main power switch on the rear panel when the receiver is not in use for a long period
of time. If used mobile, it should be noted that the AR5001D has NOT been manufactured
or tested to meet any specific mobile safety requirements. The AR5001D has no user
adjustable internal parts.
If using the AR5001D as a base station, the best short wave reception is usually achieved through
the use of a separate external earth (or ground) rod. However, consider the implications carefully if
your AC building supply uses a Protective Multiple Earth (PME) system. If in doubt, consult a qualified
electrician. Never earth (ground) to a gas pipe! The AR5001D has two antenna connectors. These
are intended for connection to a 50 ohm (unbalanced) coaxial fed antenna such as a discone, dipole,
Yagi, etc.
When installing an antenna, avoid power cables. Ensure that you do not confuse the antenna and the
I output connector as they are located close to each other.

Operating anomalies
Should the AR5001D appear to behave strangely, normal operations may be easily achieved by
performing the following steps:
1. ymptom: No control of the receiver.
Action: Turn off the power switch on the front panel. Leave it off for
approximately 10 seconds. Turn the power switch back on again.
Normal operation should be restored.
2. ymptom: The display freezes.
Action: Turn off the main power switch on the rear panel. Leave it off for
approximately 10 seconds. Turn the power switch back on again.
Normal operation should be restored.
Should the AR5001D still behave strangely, try a RESET as explained in chapter 9-13.

The following items are provided in this package:
1 AR5001D receiver

1 Operating manual (this booklet)
1 Control command list
1 2GB SD memory card
Terminology
earch & can
If you have not used a wide band receiver before or is not familiar with the terminology used, it is very
important to understand the difference between EARCH and CAN modes.
EARCH: The AR5001D provides several operations where transmissions
(active frequencies) may be automatically located by sweeping the receiver over
a wide frequency range, either from the currently displayed frequency traveling
upwards (or downwards) in a specified tuning increment (step) or by sweeping
over-and-over between two specified frequency limits. This process is known as
EARCHING. As the name implies, this process can take a long time to find
transmissions due to their ‘often intermittent’ and brief nature. or this reason, it
is best to slice large frequency ranges into smaller, more manageable pieces

9
where they may be intensely monitored.
When examining large frequency segments, it is common to find that 90% of the
frequencies are inactive and only a small number of the remaining constitute what
you really want. Searching still remains the best way to initially locate active and
interesting transmissions (in conjunction with a good frequency listing and band
plan).
CAN: Once active transmissions have been identified (either by searching or by
using a good frequency guide), it is more efficient to store the data into memories
which can be rapidly and automatically monitored in succession, stopping when
activity is encountered. This is a much more efficient means of monitoring the
most wanted frequencies as you have targeted 100% of what you most want to hear.
By contrast, searching is very inefficient for day-to-day monitoring.
Note: For the search & scan functions to operate properly, it is very important
to advance the squelch to cancel background noise. This is because the
AR 001D believes that it has found an active frequency when the squelch opens
and the “BUSY” indicator lights up. Advance the squelch control clockwise until
the background noise is just cancelled; this is known as the “threshold” position.
If the squelch control is advanced too far, weaker signals may be missed.
More details about the remarkable features of the AR5001D
High frequency (45.05 MHz) IF output
The AR5001D has a 45.05 MHz analog I output with 15 MHz bandwidth. The input signal to the 45.05
MHz I stage is directly sent to the A/D converter for digital processing. This I output signal may be
suitable as an R front end for radio signal analysis applications.
High tability Frequency tandard
When an optional GPS unit is connected, the internal reference oscillator (10 MHz) will be locked by the
GPS receiver, and the highest stability reference signal (0.01 ppm) will be obtained. This is ideal for
frequency coherent operation and D (Direction inding) applications.
DD (Direct Digital ynthesizer)
The AR5001D uses a high speed DDS for the 1st local oscillator. Unlike a standard PLL (Phased Locked
Loop) circuit for the local oscillator, the DDS enables very high speed scanning as it generates signals
instantaneously, controlled by the CPU (Micro Processor).
I/Q Digital Output (Optional)

10
The I/Q stands for In-Phase/Quadrature-Phase.
In the 45.05 MHz I stage, I/Q output is available as an optional feature. The I/Q digital signal consists of
two (2) different digital signals with phases shifted 90 degrees. The I/Q output is provided through a
continuously isochronous USB 2.0 standard interface. By using the I/Q digital output, the streamed data
can be stored on a PC hard disk for future signal analysis.
The I/Q digital output of the AR5001D has a wide dynamic range (without AGC processing) floating point
data format.
FFT (Fast Fourier Transform)
The AR5001D utilizes T ( ast ourier Transform) technology for high speed spectrum scanning.
T enables refreshment of the spectrum display more than 10 times per second for a 10 MHz span
(at 500 Hz RBW). The AR5001D scans 10 MHz of bandwidth.
LAN (Local Area Network) connection
When an optional (external) LAN interface is connected, the AR5001D can be remotely controlled
through the internet.
Triple channel reception (Receive three frequencies simultaneously)
Any frequency below 25 MHz can be received independently, separate from a frequency above
25 MHz. Therefore, two (2) separate frequencies can be received simultaneously. urthermore, any
two (2) frequencies above 25 MHz (within a range of +/- 5 MHz from the receive frequency) can also
be selected and received simultaneously. Therefore, up to three (3) frequencies can be received at
the same time.

. - DELETE
Use during the MHz frequency input to separate the MHz from the rest of the entry of kHz and Hz.
or example, the entry of 88.300000 MHz would be [8][8][.][3] [MHz].
Note Frequencies below 3.0 MHz (3000 kHz) are always displayed as kHz regardless of input format.
In memory mode, press the [FUNC] key, and press the [.] to display the memory channel to be deleted.
Press the [FUNC] key, and then press and hold the [.] key for two seconds to activate the delete menu.

to configure the LP (Low Pass ilter), HP (High Pass ilter), De-emphasis, and CW pitch frequency.
TEP - AGC
Press this key to select the frequency step size for tuning the receiver. If “AUTO” is displayed on the LCD,
the frequency step will automatically be determined from the receiver’s bandplan.
To change the frequency step, press the [ TEP] key. Rotate the sub dial to select the desired frequency
step, and then press the [MHz] key.
Press the [FUNC] key, and then press the [ TEP] key to activate the AGC (Automatic Gain Control)

configured in the M mode.
When AGC is set to O , two horizontal bars are displayed on the LCD above the “kHz” or “MHz” icon.
PA – . ET
This key is used to PASS (skip over) unwanted active frequencies in search mode and scan mode.
