5.0 Application

Before placing into operation, see Safety and
Regulatory Information on page vii.

The Model 4610 Royce Field Site Source is a portable self-contained comb
generator. This device can be used as an aid for maintaining the integrity of a
test site and the accuracy of test results. By comparing daily test site
measurements with the original reference measurement, sources of unexplained
variances due to the test site and test equipment can be more easily identified.
Using the Model 4610 does not take the place of periodically performing site
calibration per the FCC, VDE, or MIL-STD requirements. To establish a
reference for an individual test site (indoor or outdoor), the Model 4610 is placed
on the test site in the area normally occupied by the Equipment Under Test
(EUT). Power is applied to the unit by depressing the power switch. The power
switch will show a green color, indicating the power switch is in the On position.
Also, the power on indicator light will be illuminated. The Model 4610 is now
radiating a comb of signals between 10 MHz and 600 MHz, spaced at 10 MHz
increments. Using an antenna and a spectrum analyzer or receiver, the
frequency and amplitude of each signal point is recorded. This initial
measurement becomes the reference point for all future site measurements. The
accuracy of the Model 4610 can be verified by removing the transmitting rod and
connecting the output connector to a spectrum analyzer.

The Model 4610 is not a licensed transmitter; therefore, the output power level is
extremely low. A preamplifier is required on the output of the receiving antenna to
amplify the output signals from the Model 4610. A 26-dB preamp is
recommended for this purpose. Radiated Emissions from Open Area Test (OAT)
Site on page 25 shows a typical spectrum analyzer output plot of the signal
pattern from the Model 4610 using a 26-dB preamp. This is the type of signal
pattern found on an Open Area Test (OAT) site.

Application Note: Voltage-Selectable Battery Charger

Part Number: 102615, Rev A

Date: May 25, 1993

BATTERY CHARGER OPERATION

The ETS-Lindgren voltage-selectable battery charger is solely intended for
charging the sealed lead-acid batteries found in ETS-Lindgren products. The
battery charger is a means of providing the necessary charge voltage and current
from either a 115 VAC 50/60 Hz or 230 VAC 50/60 Hz source.

It is necessary to select the proper input voltage prior to connecting
the battery charger to the power mains. The voltage select switch is
located adjacent to the power input receptacle.

To maintain safety requirements, use the CSA-certified power cord provided. If it
is necessary to provide other means of attaching the battery charger to the power
mains, it is required that a Type HD 21 (PVC cord) or Type HD 22 (rubber cord)
with a nominal cross-section of 0.75 mm

2

be used.

The battery charger provides both fast and trickle charge operation. Switching
from one charge mode to the other is provided automatically by the charger. The
front panel indicator marked FAST CHARGE illuminates when the battery
charger is in the fast charge mode. When the POWER ON light is illuminated and
the FAST CHARGE light is extinguished, the battery charger is in the trickle
charge mode.

Always remove mains power before opening
the housing.

The battery charger is protected against overcurrent by a 200 mA 250 VAC
time-delay fuse. If it becomes necessary to replace the fuse, use a fuse of the
same type and rating to maintain safe operation. The fuse is accessible by
removing the two Phillips head screws on the underside of the unit. The output of
the battery charger is protected against overcurrent conditions by use of
fold-back circuitry.

6.0 Installation and Operation

Before connecting any components, see Safety
and Regulatory Information on page vii.

The Model 4610 Royce Field Site Source generates a 10 MHz fundamental
frequency and harmonics at 10 MHz increments up to 600 MHz. A rod antenna is
provided which should be connected to the Type N connector located on the top
of the unit. This Type N output can also be connected to a spectrum analyzer to
verify performance of the unit.

Power to the Model 4610 is provided by rechargeable sealed lead-acid batteries
(two are provided at six volts DC each). In the detented position of the power
switch, power is provided to the unit and a power on indicator should be
illuminated. When battery voltage discharges to a predetermined minimum level,
a low battery indicator will illuminate (should the batteries experience a deep
discharge, neither light will be illuminated). At this point, the power switch should
be placed in the Off/Charge position and batteries charged using the
charger port located adjacent to the power switch. Charging can be made with
either the 100 VAC/60 Hz charger or the optional 220 VAC/50 Hz charger.
