S-4068A Sweep
Generator (Wobbulator) covers the 0.4 to 465MHz sweep range
with synthesized, comb and external markers. It is a versatile equipment
for education covering the Radio, TV, VCR and Cable TV syllabus
applications. Students can printout the response curves for their
lab journals viat the centronics interface on an epson lx800 or
compatible printer. |
