1INTRODUCTION
The IRIG-B Analyzer helps you decode and validate your IRIG-B timing signals, automatically handles
optical or multilevel copper signal inputs and is battery powered with an easy to read backlit LCD
display, ideal for use in areas with poor lighting.
It comes complete with all components required for IRIG-B measurement including an optical
converter, a BNC-Tee and test leads to measure copper-based IRIG-B signals.

5POWERING ON THE IRIG-B ANALYZER
Pressing the Power button will turn the IRIG-B Analyzer on. During start up, an initialization
screen with the Serial Number will be shown for a short time. Refer to Figure 8
Figure 8: Startup Screen
Once initialized, the IRIG-B Analyzer will display theHome screen as below in Figure 9
6HOME SCREEN
Whilst in this state the unit will start searching for both fiber and copper IRIG-B inputs. Whilst
searching for a valid input signal, the analyzer will transition between different status screens
(Figure 9).

7MEASURING COPPER IRIG-B SIGNALS
Warning: The IRIG-B signals to be measured can be at a voltage level that presents a shock
hazard. Care should be taken when doing these measurements to avoid touching any
exposed terminals.
If the IRIG-B signal being measured exceeds 48V (AC or DC), then a High Voltage symbol will be
displayed at the top of the screen as in Figure 10 below.

Figure 10: High Voltage warning display
1. To measure electrical IRIG-B signals connect the two test leads to the IRIG-B Analyzer as
shown in Figure 11. Ensuring that the red plug is inserted into the red socket, and the black
plug is inserted into the black socket.
Figure 11: Test leads connected ready to read copper IRIG-B signals
2. Hold the probes to the exposed IRIG-B cabling test point ensuring the red lead is connected
to the positive and black to the negative side of the IRIG-B signal.
3. The IRIG-B analyzer will detect if an IRIG-B signal is present and display the screen in
Figure 12 for 1 second.
Figure 12: Signal detection screen
4. The IRIG-B Analyzer will display the signal properties as shown in Figure 13, the arrow keys
can be used to navigate through the listed details.

Note: A full description of the signal properties displayed on the details screen can be seen in the
Appendix.
When viewing the Details screen you can press F2 to return to the HOME screen to re-test the
IRIG-B signal.
8MEASURING FIBER IRIG-B SIGNALS
SC Fiber Cable
1. Remove the protective plug from top of IRIG-B analyzer to expose the SC fiber socket as per
Figure 14 below.
Figure 14: SC Fiber socket with protective plug removed
2. Connect the IRIG-B SC fiber cable to the IRIG-B Analyzer ensuring the tab on the fiber plug
matches the notch in the fiber socket as shown below in Figure 15 below.
