Performance Tests – Option 011
16. Source and Receiver Harmonics (Option 002 Only)
In Case of 
Difficulty 
WARNING These servicing instructions are for use by qualified personnel only. 
To avoid electrical shock, do not perform any servicing unless you  are 
qualified to do so.
WARNING The opening of covers or removal of parts is likely to expose 
dangerous voltages. Disconnect the instrument from all voltage 
sources while it is being opened.
WARNING The power cord is connected to i nternal capacitors that may remain 
live for five seconds after disconnecting the plug from its power 
supply.
1If the analyzer fails the channel A compression test, suspect the A5 A sample 
assembly. Repeat this test. Replace the sampler assembly if the problem still 
exists.
2Suspect the A6 B sampler assembly if the analyzer fails the channel B 
compression test. Repeat this test. Exchange the sampler assembly if the 
failure still occurs.
16. Source and Receiver Harmonics (Option 002 Only)Perform this test to determine the 2nd and 3rd harmonics of the source, 
receiver, and the source/receiver combination.
