Overview of the Test Set’s Built-In Tools
Using the RF Tools Program
Each RFTOOLS test includes two parts: calibration and measurement. 
If the spectrum analyzer performs a self calibration between the 
calibration and measurement of the RFTOOLS test, the spectrum 
analyzer’s automatic self calibration instability will increase RFTOOLS 
test measurement error. To avoid this problem, you may use this menu 
item to turn off the spectrum analyzer’s self calibration. This self 
calibration should only be turned off after the unit has reached a 
constant powered-on operating temperature (approximately 30 minutes 
after power-on), therefore it is probably best to leave it on. After 30 
minutes, turning the self calibration off will improve the measurement 
accuracy of RFTOOLS tests. 
Catalog PC (Memory) Card
This utility lists all the files contained on the PC card. The PC card that 
you want to catalog must be inserted prior to selecting this test. 
File types are denoted by the following suffixes: 
• .PGM suffix denotes a program code file 
• .LIB suffix denotes a library file 
• .PRC suffix denotes a procedure file 
• .DAT suffix denotes a data file 
• .PLT suffix denotes a plot file
