The LSG-215A is Standard Signal Generators using the synthesizer system for generating CW and FM/AM modulation signals of (A) 30 to 120 MHz and (B) 100 kHz to 30 MHz. 2. FEATURES (1) Highly stable signals are available as the oscillation signal is locked to the reference crystal oscillator. (2) Output level can be set in a range of —10 to 120 dBμ (0 dB=lMV) in 1-dB step. (3) Using an internal memory, which is battery backed up, 100 points of selections combining frequency, modulation type, and output level can be stored. (4) Frequency and output level settings are available by ten-key operations. (5) The peak indication system is used for the meter circuit, and thus the composite signal can also be accurately indicated. (6) Using a separately available memory, EPROM (2716 type), settings of predetermined frequencies for a service station or production line can be conveniently made. (7) Remote control is available for the operations such as the memory call, using the 36-p connector on the rear panel.
