Edit PP Types Menu
This menu allows the configuration of the values for a selected PP type.
The first field which can be edited is the type name. This can be any alphanumeric string of up to 30
characters.
The "Dummy If Traffic" field specifies whether a dummy bearer should be transmitted after a connection
has been established. This is required by some portable parts in order to maintain synchronisation.
Configurable values for this field are "No" remove dummy bearer after connection is established, or
"Yes" do not remove dummy bearer after connection is established.
The fields "Q0", "Q3", and "Q6" define values for the MAC layer Q-packets transmitted by the CTS60
when in PP test mode. Each is defined as a series of hexadecimal values which correspond to a Q-
packet message, it should be noted however that not all of these are transmitted to the signalling.
Further details of these messages can be found in the ETSI standard ETS 300 -175 part 3.
The packet type defines the type of packet that will be assumed for power ramp and RF modulation
measurements. P32Z is a packet with 16 bits for the preamble and synchronisation fields of the burst.
PP32Z is a packet with 32 bits for the preamble and synchronisation fields of the burst ie. Prolonged
preamble.
Input and output attenuation values can also be entered. These specify the characteristics of the coupler
used to connect the portable part to the CTS60 and will be used when calculating power levels.
Any RF transmit level configured on the CTS60 will represent the actual level received at the portable
part after the output attenuation has been allowed for. This means that the RF level actually emitted by
the CTS60 is higher than the displayed value by the magnitude of the output attenuation.
The input attenuation will be applied to power measurements to ensure that these are calculated
correctly allowing for the attenuation of the coupler.
It is important to use the correct antenna coupler so that the input RF Level is inside the allowed range
for the connector being used (refer to the technical information section for the allowed RF range). The
attenuation/gain value of the coupler should then be configured for the FP (or PP) type being used (see
Selecting and Configuring Types
), so that the software can compensate for the attenuation and display
the real value. Failure to do so may result in the CTS60 displaying incorrect values.
