Chapter 1 Introduction
Purpose and Function
The Bird 4042E Series Channel Power Sensors are digital power sensors. The
4042E Series Channel power sensors are typically used to measure forward and
reflected average power on a 50 ohm RF transmission line in a frequency band
with an overall range of 100 to 1000 MHz. There are two maximum forward
power measurement options 50 or 500 watts with reflected power max 10 dB
below the forward Power levels, the 4042E sensor also provides VSWR readings.
See "Model Identification" on page 21 .
Figure 1 Bird 4042E Sensor
The 4042E Power Sensor uses Ethernet communications for sensor control and
measurement data.
See
"Sensor Operation" on page 9 .
The 4042E Sensor is designed to transfer data over an Ethernet connection. The
power sensor requires an external power supply.
Each sensor is equipped with RF input and output connectors, one RJ-45
connector for Ethernet communications, a PTT connector, and a status indicator.
See

Channel Sensor Operation
The 4042E Channel Sensor is a unique sensor that is able to measure the
forward power, reflected power and VSWR of a SINGLE CHANNEL in the
presence of multiple channels at the output of a frequency combiner (see
Figure 5 on page 6 ).
The sensor can also measure the forward power, reflected power and the VSWR
of the composite signal by scanning up to 16 individual channels and summing
their power, see
Figure 3 .
Figure 3 Channel Sensor Configuration
Once connected to an RF Transmission line, the sensor may be programmed to
measure power and VSWR for up to 16 frequencies or channels.
The bandwidth of each channel is selectable and may be set to one of the
following values:
6.25 kHz
12.5 kHz
25 kHz
The sensor can be setup to provide low power and VSWR alarms for all 16
channels monitored by the 4042E Sensor.

Ethernet Measurement Interface
The 4042E sensor displays measurement information on a Web UI. Using a web
browser, enter the Ethernet IP Address for the 4042E to display the web page.
Table view displays the composite Forward, Reflected, and VSWR measurements
and the same measurements for each configured channel. See
Figure 4 .
Figure 4 Web UI, Table View Measurement Display
Ethernet IP Address
Each 4042E leaves the factory with the same default IP Address.
Default IP Address: 192.168.3.200
To change the IP address see
"Set IP Address" on page 17 .
PTT
PTT is used to prevent false alarms during periods when the transmitter is not
transmitting. PTT disables alarm detection when the transmitter is off. Alarm
functions will only be possible when the transmit button is engaged.
PTT may be set to normally open or normally closed logic. The PTT terminals
must be in the correct logic state for PTT to operate correctly.
Note: PTT input is a passive connection and requires a 5V TTL
signal to operate.

Chapter 2 Power Sensor Installation
The Bird 4042E Series Channel Power Sensors are designed to be used for
continuous power monitoring in multiple Land Mobile Radio (LMR) systems. The
4042E can provide real-time RF forward and reflected power and VSWR
measurements.
Ethernet Connection
The Ethernet connector is used to connect the 4042E to a PC or a network
router/switch. Measurement data is transported over the Ethernet connection
so the data can be viewed in a web browser. The configuration depicted in
Figure 5 is an example of one possible installation.
Since the 4042E is shipped with a static IP address, before more than one unit
can be added to a LAN, the IP address must be changed to a unique static IP
address or set to DHCP.
Direct PC Connection — A direct PC connection is a connection between a
PC and a single 4042E. This connection can be used to view the sensor’s
measurement data, however, if the sensor will be used with a LAN connection,
this type of connection must be used to change the IP address of the 4042E. See
"Direct PC Ethernet Connection" on page 6 .
LAN Connection — The 4042E may be connected to a router or switch so it
can provide measurement information through a LAN. A LAN connection can
provide the ability to monitor several 4042E sensors from a single PC.
Additionally, SNMP management software can be used to aggregate multiple
sensors and monitor their outputs. See
"LAN Connection" on page 7 .
