Safety Considerations
General
This product and related documentation must be reviewed for familiarisation before operation. If
the equipment is used in a manner not specified by the manufacturer, the protection provided by
the instrument may be impaired.
Before Applying Power
Verify that the product is set to match the available line voltage and the correct fuse is installed.
Before Cleaning
Disconnect the product from operating power before cleaning.
WARNING
Bodily injury or death may result from failure to heed a warning. Do not proceed beyond a warning
until the indicated conditions are fully understood and met.
CAUTION
Damage to equipment, or incorrect measurement data, may result from failure to heed a caution.
Do not proceed beyond a caution until the indicated conditions are fully understood and met.
This equipment must be earthed
An uninterruptible safety earth ground must be maintained from the mains power source to the
product’s ground circuitry.
WARNING
When measuring power line signals, be extremely careful and use a step down isolation transformer
whose output is compatible with the input measurement capabilities of this product. The product’s
front and rear panels are typically at earth ground. Thus, never try to measure AC power line signals
without an isolation transformer.
WARNING
Instructions for adjustments when covers are removed and for servicing are for use by service-
trained personnel only. To avoid dangerous electrical shock, do not perform such adjustments or
servicing unless qualified to do so.
WARNING
Any interruption of the protective grounding conductor (inside or outside the instrument) or
disconnecting of the protective earth terminal will cause a potential shock hazard that could result
in personal injury. Grounding one conductor of a two conductor out-let is not sufficient protection.
Whenever it is likely that the protection has been impaired, the instrument must be made
inoperative and be secured against any unintended operation.
If the instrument is to be energised via an autotransformer (for voltage reduction) make sure the
common terminal is connected to the earthed pole terminal (neutral) of the power source.
Instructions for adjustments while the covers are removed and for servicing are for use by service-
trained personnel only. To avoid dangerous electrical shock, do not perform such adjustments or
servicing unless qualified to do so.
For continued protections against fire, replace the line fuse(s) with fuses of the same current rating
and type (for example, normal blow time delay). Do not use repaired fuses of short-circuited fuse
holders.

Cleaning Instructions
To ensure long and trouble operation, keep the unit free from dust and use care with liquids around
the unit.
Be careful not to spill liquids onto the unit. If the unit does get wet, turn the power off immediately
and let the unit dry completely before turning it on again.
Clean with a damp (with water) cloth.
Never spray cleaner directly onto the unit or let liquid run into any part of it. Never use harsh or
caustic products to clean the unit.

Operating Procedure
Introduction
The Quartzlock model E5000 is a distribution amplifier designed for standard frequency distribution
between 1 MHz and 100 MHz.
Input
One input is provided. This has input impedance of 50 Ohms. The input level can be between
-5dBm and +13 dBm.
Outputs
The E5000 configurable up to 24 outputs. These have source impedance of 50 Ohms, and will
provide between +5 and +13 dBm (MAX) into a 50 Ohms load.
Front panel LED Indicator and Status
Blue LED: Power ON/OFF switch
Green LEDs: ON: Input signal is present and channel is operating correctly.
OFF: Input signal is not present, or channel has failed.
