AM / FM Signal Generator

DDS Signal Generator

AM/FM Signal Generator (AFM-250D) is compact and rugged instrument. Generator continuously variable from 10KHz to 250MHz with low spurious output & harmonics with negligible RF radiations. An outstanding width of the generating Frequency range provides the users with various applications, including tests and adjustments of  Receivers, Amplifiers, CATV Equipments, etc.
Frequency Range : 10 KHz to 250 MHz
Display : 16x2 alphanumeric LCD with backlight with resolution better than
1KHz(Optional 1Hz)
Stability : 1 KHz ± 20 ppm / 5 min after warm up of two hours
Leakage :   Less than 1 micro volt induced in 2.5 cm dia loop kept 2.5 mm away  
from surface of instruments is less than 2 uV.
Spectral Purity : Harmonics - Less than - 26 db 
                      AM on CW - Less than  - 46 db (0.5%)
                      FM on CW - Less than - 200Hz
                      AM on FM - Less than 5% upto 30 KHz internal FM
                      FM on AM - Less than 500 Hz at 30% internal AM
