Step 1: System Settings Bistatic Setup
When operating in Bistatic mode, the antennas can be plugged into the system in the following
configurations;
•
Channel 1 transmitting to Channel 2. Channel 2 will also function as a Transmitter\Receiver in dual
receiver mode
•
Channel 3 transmitting to Channel 4. Channel 4 will also function as a Transmitter\Receiver in the
dual receiver mode.
Note:
Bistatic operation will not function correctly across channel groups. Channel 1 and Channel 2 are
one group; Channel 3 and Channel 4 are the second group. An antenna connected to Channel 1 cannot act
as the transmitter for an antenna that is connected to Channel 3 or Channel 4 as the receiver.
In the following setup description, the setup will use Channels 1 and 2. After the User has selected the
desired linear units from the SIR 30 Start screen, the SIR 30 will display the SYSTEM SETTINGS menu
shown in Figure 113 below.
Note:
In a bi static only setup where two shielded antennas (2.6 GHz, 2 GHz, 1.6 GHz 1 GHz, 900 MHz,
400, 270, 200 MHz) are being used as separate transmitter and receiver, the system will use channel one
(1) as the transmit channel and Channel two (2) as the receiver channel. In this type of configuration, only
one (1) channel will be active in the data collection display.

1
Distance Control:
The User should enter the desired horizontal scan density and mark spacing.
2
Unit/Mark:
The User should enter the desired units per mark. This controls the spacing of Distance
Marks written into the data file and onto the data acquisition screen during data collection
3
Max Units/File:
This is the total expected length of the data file in linear units. If the User knows the
file length prior to data collection then enter the value, otherwise leave this value at zero (0).
