1.6 Power Adapter
The SLM 1479 is supplied with a DC power supply that is used to power the instrument
and to indirectly charge its internal battery. The power supply/adapter is a regulated 12
VDC with a positive center terminal on the connector to the instrument. The power
supply is rated for ACV inputs ranging from 100-240 VAC @ 50/60 Hz and can deliver
up to 3.0 amp of DC output current.
The Power Supply/Adapter provided with the SLM 1479 meets industry and safety
regulatory standards. This insures safe instrument operation. Therefore, it is
recommended that you use only the provided Power Adapter.
NOTE: When powering the SLM 1479 use only the supplied Power Adapter or a power
supply/adapter which strictly meets all technical specifications and industry safety (CE,
UL etc) requirements.
1.7 Battery Charging/Management
The latest battery technology, hyper lithium polymer (Li Po) battery, powers the SLM
1479 for portable testing applications. The battery pack provides years of dependable
service. The battery pack requires no routine maintenance but it is advisable to be
familiar with some handling, charging, storing, and disposal characteristics.
Some charging management practices may extend the battery pack’s useful life. Also
the SLM 1479’s power management features may provide added use time on a single
charge. This section covers the meter’s battery condition indicator, battery charging
recommendations and battery power management features.
When operating from the battery, a battery indicator icon at the bottom left of the
measurement screen indicates the remaining battery charge. Battery indicators include a
full charge 100%, 80%, half charge 50%, 30%, and
10% charge indicators. The presence of the battery
icon indicates the meter is operating under battery
power. When the power supply/adapter is used to
power the meter, the battery icon is replaced by an AC
plug icon.
The SLM 1479 uses a special battery charging/management circuit to monitor and
manage battery charging. Battery charging is managed by the meter‘s charging circuits
Page 13 (124)
SLM 1479 User Manual
with sensors inside the battery pack. You should never remove the battery and attempt
to charge the battery with an adjustable power supply.
A Li Po battery contains no memory or conditioning affects like other battery
technologies so a full discharge and recharge cycle is not beneficial. After use, it would
be advisable to charge the battery. If used daily, charge the battery pack every night for
best battery life.
Avoid a complete discharge state or prolonged low charge of the battery as this can
have an adverse effect. Charge the battery after continuous use in which the battery
charge is low or depleted. Also, Li Po batteries gradually discharge over a very long
period of time (> 4 months) when stored or not used. Recharge the battery every 3-4
months when not used or in storage. NOTE: Do not leave the battery in a discharged
state. If stored, or not used, periodically charge the battery.
Battery operating time varies considerably depending on use and power management
settings. Expect approximately 4 – 5 hours depending on power management settings
and LNB powering. To extend the useable battery measurement time on a single
charge, the SLM 1479 offers three power management features including: 1) Unit Auto
Off, 2) Display Light Timer and, 3) Backlight Brightness. Please see the METER
CONFIGURATION Menu (Section 3) of this manual for details on these settings. For
maximum battery use time, set the BATTERY SAVING setting to the “ON” position. A
lower display backlight brightness level greatly extends battery use time. Set the
BRIGHTNESS setting as low as you can, depending on your tolerance for display
brightness and the light in the testing environment.

Page 29 (124)
SLM 1479 User Manual
3.23.1 LNB L.O.
The meter LNB L.O. (Low Noise Block Converter - local oscillator) frequency is typically
used for settings associated with the Satellite receiver and dish settings. However, the
LNB L.O. feature is made available in the TV and CATV reception settings in the rare
case that an LNB L.O. input is required for a frequency conversion of the received
signal. The default setting is 0 MHz which results in no frequency conversion. If the LNB
L.O frequency is set or selected, the meter performs the frequency conversion
subtracting the lower frequency from the larger frequency.
Note: If the LNB L.O. frequency is not the default 0 MHz, the frequency readout in the
meter’s measurement screen will indicate improperly for the known broadcast or cable
channel frequency. The frequency indication is higher or lower by the entered L.O.
frequency value.
3.23.2 SNR LINE
The SNR LINE field is relative to measurements of analog channels only. The SNR
(Signal-to-noise-ratio) measurement is a measured ratio of the video noise compared to
the video amplitude or voltage. The ratio is calculated as a ratio of noise to signal
voltages in dB.
The integrated video waveform monitor for analog channels is used to measure the
SNR. The measurement is calculated using a single scan line of the detected video
modulation of the selected channel. The SNR LINE field provides selection of the analog
channel video scan line in which the meter performs the signal-to-noise ratio
measurement. The selected line must be void of any test signal or vertical interval data
as this would degrade or reduce the measured SNR measurement. The default line is
line 21. To select a different line, touch the SNR LINE field. Rotate the large control knob
to increment to the desired line. Push in the large knob to enter the selected line.
3.23.3 DISCOVERY
The DISCOVERY field provides an indication of the signal type(s) the meter searches for
