NOTE: This lead / appliance must only be wired by competent persons
WARNING: THIS APPLIANCE MUST BE EARTHED
IMPORTANT: The wires in this lead are coloured in accordance with the following code:
Green/ Yellow: Earth
Blue: Neutral
Brown: Live (Phase)
As the colours of the wires in main leads may not correspond with the colours
marking identified in your plug/appliance, proceed as follows:
The wire which is coloured Green & Yellow must be connected to the Earth
terminal marked with the letter E or by the earth symbol or coloured Green or
Green & Yellow.
The wire which is coloured Blue must be connected to the terminal which is
marked with the letter N or coloured Blue or Black.
The wire which is coloured Brown must be connected to the terminal marked with
the letter L or P or coloured Brown or Red.
If in doubt, consult the instructions provided with the equipment or contact the
supplier.
This cable/appliance should be protected by a suitably rated and approved HBC
mains fuse: refer to the rating information on the equipment and/or user
instructions for details. As a guide, cable of 0.75mm2should be protected by a 3A
or 5A fuse. Larger conductors would normally require 13A types, depending on the
connection method used.
Any moulded mains connector that requires removal /replacement must be
destroyed by removal of any fuse & fuse carrier and disposed of immediately, as a
plug with bared wires is hazardous if a engaged in live socket. Any re-wiring must
be carried out in accordance with the information detailed on this lable.

CENTER FREQ
This field is the value for the frequency located at the mid-point (center screen) of
the selected span. This frequency value may be changed by entering the digits,
decimal point, followed by the ENTER or MHz key, or the Íand Îkeys can
select a digit to increment or decrement using the SPINNER.
The range of valid entries is 0.010MHz to 1000.000MHz. Setting the Center
Frequency may change the Span field if the span must be lowered to include the
desired frequency. For example, if the Span is set to 100MHz/div and the Center
Frequency is changed to 50MHz, the span will change from 100 MHz/div to 10
MHz/div.

SPAN
This field is the value for the frequency range covered by the GSP-810 as it
sweeps its receiver. This span value may be changed by the SPINNER to roll
through the list of valid spans.
The range of valid entries is 2 kHz / division through 100 MHz / division plus zero
span (0 Hz / div). If changing SPAN will cause Center Frequency to change, the
“Limt” message will appear on LCD. It means that the SPAN has exceeded the
frequency range for Center Frequency setting. For example, if the Center
Frequency is 25MHz and the Span is changed from 5MHz to 10MHz, a “Limt” will
appear because the start frequency of span has exceeded the frequency range of
GSP810.

This field sets the Resolution Bandwidth. The RBW will be set to the optimum
automatically every time when SPAN selection is changed. Afterward RBW can be
set by rotating the SPINNER to scroll through the list of valid RBWs. It has been

MARKERS
The GSP-810 supports 2 markers. To access the marker screen, press the MRK
key. Displayed will be 2 marker frequencies. Accessing the marker frequency
fields is performed through the left column of numbers. Cursor to the left most
position, then use the SPINNER to switch between marker 1 and marker 2.
Pressing ENTER will also switch between the 2 marker fields. The frequency
value may be changed by entering the digits, decimal point, followed by the
ENTER key, or the Íand Îkeys can select a digit within a marker to increment
or decrement by using the SPINNER. The valid range of entries is 0.000 MHz to
1150.000 MHz.
A marker will appear on the CRT when the marker frequency selected falls within
the range of frequencies defined by the main screen Center Frequency and Span.
For example, if the center frequency selected is 100.000 MHz and the span is 1
MHz per division, a marker will appear on the screen if the marker frequency is
anywhere between 95 MHz and 105 MHz. When the marker is displayed on the
CRT, the signal level at the location of the marker will be displayed to the right of
the marker frequency. This level will continuously update while in the marker
screen. If the marker frequency is outside the range of frequencies for a given
Center Frequency and Span, a message will indicate its status. If the marker
frequency is too high to be displayed on the CRT, instead of the marker level, “Off
(high)” will be displayed. If the marker frequency is too low, then “Off (low)” will be
displayed. If the Markers are disabled, then “OFF” is displayed. To disable the
markers, simply press the Marker key while in the markers sub-screen.
If the markers are enabled, their position on the CRT will be updated on each
Center Frequency change and each Span change. If a Center Frequency or Span
is selected such that the marker moves off the CRT screen, they will be off until the
parameter is changed to allow the marker to re-appear.
The resolution of the marker on the screen is based on the span selected. There
are 50 positions between major divisions on the CRT that a marker can be moved
to. In the 100 MHz/div Span, for example, every 2 MHz will move the marker 1
position. On the outside edges of the trace, however, the maximum and minimum
marker positions are considered out of range.

PK->MKR
This is a peak search function. Using marker 1, the GSP-810 begins at the current
marker 1 frequency and scans for a peak. When a peak is found in the trace, the
marker frequency is updated to show the frequency of the signal and the level of
the peak is also displayed. If no peak is found (that is greater in frequency than the
current marker position), the marker stops at the end of the trace. Another press of
the PK->MKR key will start a new search from the frequency point at the left-most
edge of the span. If the marker is not active, it will be activated and a new search
will begin from the frequency point at the left-most edge of the span. If the marker
is active but the bottom half of the LCD display does not show the marker, the peak
function will still complete and the marker on the CRT can be viewed.

DELTA MARKERS
The delta marker function is similar to the marker function. To access the marker
screen, press the ΔMKR key. In this function marker 1 is used as the reference
marker level and the marker 2 level is level difference between marker 1 and
marker 2. In the meantime, a “Δ” symbol will also be displayed on the LCD display.
MKR->CF
This function moves the Center Frequency to the current Marker 1 frequency. This
will occur even if the marker is OFF. The span may be adjusted as required for the
Center Frequency. It has no effect if the current span selection is zero span.
