It comprises of a Full Band Sweep Generator covering VHF, MIDBAND & UHF and built-in Marker Generator.
VHF - 13 channels are covered, TV IF and CH1 to CH12. Three synthesized pulse markers at Vision, Centre and Sound frequency of each channel.
MIDBAND - 12 Midband channels are covered, S1 to S12. Three synthesized pulse markers at Vision, Centre and Sound frequency of each channel.
VHF Full Band Sweep - 1 Band covers the 1-240MHz sweep range. 10MHz Xtal Comb Markers are available.
UHF Full Band Sweep - 1 Band covers the 450-860MHz sweep range. Variable birdy marker available over the whole range, freq is digitally readout on 5 digit LED display.
EXT Marker - Variable Marker can be generated over the entire sweep range at the frequency of an externally connected sinewave input.
