8700 Frequency Source/Measure GPS Standard
Introducon
The 8700 Frequency Source / Measure GPS Standard has been designed to able to calibrate
all functions of modern hand held and bench frequency counters and signal sources. A high accuracy
precision GPS reference frequency of up to 1 GHz is available, with outputs for A-B phase and
variable levels for confirming trigger levels of modern counter-timer units
In addition, unlike other GPS references, the 8700 also adds the ability to measure frequencies
of up to 1 GHz with high precision, removing the requirement for an additional instrument in your
laboratory. Utilising the latest in GPS reference technology, the 8700 combines both frequency source
and measurement into a single integrated solution.
A full colour 7.2” LCD screen provides the user with a comprehensive source / measure readout,
with direct access to detailed settings and satellite signal information.
Main Features
• Precision 10MHz output synchronised to GPS reference enabling traceable frequency output anywhere
in the world with no requirement for external calibraon.
• Digitally divided frequency output from 1 Hz to 5 MHz in 1,2,5 steps internally disciplined to GPS
referenced 10 MHz.
• 5V peak-peak square wave frequency output from 10 Hz to 2 MHz.
• Variable level sinewave output into 1 MΩ (1mV to 5V) or 50Ω (1mV to 2.5V) from 10Hz to 2MHz.
• High Frequency output from 10 MHz to 1.05 GHz internally disciplined to GPS.
• Frequency measurement from 1 Hz to 1 GHz, internally disciplined to GPS.
• A-B output for verifying phase meters with output from 0° to 359° at frequencies from 1 Hz to 50 kHz.
• A full colour 7.2” LCD screen ensures clear display of measurements, outputs and menu funcons.

8700 Operation Manual
Preparing the Unit for Use
Inial Inspecon
After shipment the standard should be inspected for any signs of external damage. Should
external damage be found contact the carrier immediately. Do not connect a damaged instrument to
the line power as this may result in internal damage. Please retain the original packaging; this should
be used when returning the standard for service.
Ensure that all external calibration seals are intact and show no sign of tampering.
Posioning the Standard
The standard should be placed where access to both front and rear connections is not
hampered. Transmille advise that at least 5cm clearance is allowed to the rear to allow the passing of
power cables to the input is allowed.
Posioning the Antenna
To operate correctly the 8700 requires a GPS antenna with full view of the sky to achieve a
stable lock with GPS satellites.
A range of antennas with varying cable lengths are available for purchase from Transmille with
magnetic backing to affixing to the exterior of buildings.
Although it may be possible to receive GPS lock with the antenna mounted internally (for
example near a window) Transmille would advise that the antenna is fixed permanently outside to
ensure a stable lock, especially in built up areas.

8700 Operation Manual
Rear Panel Connecons
Connections are offered on the rear panel of the 8700 as below
On the rear USB, RS232, RJ45 and GPIB connectors can be used for controlling the instrument
remotely. A BNC connector is provided for the GPS antenna input (labelled), 1 PPS output and
dedicated 10 MHz out.
If specified, an option to have 5 additional buffered 10 MHz outputs will be provided each with
independant BNC connectors
Due care should be taken to prevent damage to the internal pins of the BNC connectors by
using only undamaged male BNC cables to connect.
Seng and checking the line voltage
The standard has been designed to work from either 110-120V or 220-240V line supply.
The user should confirm that the correct voltage has been set prior to connecting power to the
instrument. Connecting the instrument to the wrong power supply could cause damage to the
instrument. To change the line voltage, remove the fuse / voltage selector housing from the rear
of the unit, rotate through 180° and replace with he required voltage setting at the bottom of the
housing.
The instrument is set for 110V operation when shipped to the USA, for all other regions the
instrument is shipped set to 230V operation.

8700 Operation Manual
Powering up the Instrument
After connecting line power, the instrument can be switched on with the power switch on the
rear of the instrument.
The front panel display will illuminate and the instrument will begin its start up sequence. This
process takes approximately 15 seconds. After powering on, allow the unit to acquire a GPS fix, as
identified on the front panel prior to use.Connecting to a computer
The 8700 is fitted with USB, RS232, GPIB and Ethernet interfaces for connecting to a computer.
For best compatibility with ProCal, Transmille advise that the USB connection is used.
