ALTERNATE/DELAYED SWEEP
Delayed sweep allows a segment of the Main (A) sweep to be expanded using a shorter B sweep that is placed in position with the DLY (delay) control. The time span of the B sweep is shown highlighted on the A trace and the B trace can be observed by itself. Alternate sweep shows both the highlighted A trace and the B trace simultaneously. With 3 channels and alternate sweep in use, a total of 6 traces can be set up (8 traces if CH1, CH2 sum or difference is also selected). Delay time for the B trace appears on-screen in the Model 8105.
SYNCHRONIZATION
The sync reference may be sourced from channel 1, 2, 3 or the power LINE. But with the SOURCE set to VERT the selection is automatic and depends upon the channel(s) in use. Sync MODE settings include AUTO, NORM, FIX and SINGLE. The FIXed mode tracks signal amplitude to keep the trigger point within the p-p span and maintain hold despite level changes. Coupling choices include AC, HF REJ, DC, TV-V and TV-H. The last two employ dedicated sync separators to ensure rock-solid video waveforms.
EXTRAS
Features worthy of consideration include X-Y operation needed for Lissajous patterns of stereo signals or setup of raster displays, triggered-delayed sweep where the B trace waits for the next trigger after the delay time. In SINGLE SWEEP the trace is armed and ready to catch random or one-time events. CH1 output (rear panel) allows the CH1 amplifier to be used as a high-gain, calibrated preamp. Z-AXIS INPUT (rear panel) for blanking and/or marker-spot injection in sweep work and in raster displays and an internally etched illuminated graticule with continuously variable ILLUM control.
KEY POINT
Models LS 8106 and LS 8105 share common specifications And operating features except that the LS 8106 offers auto setup, solid state attenuator switching, on-screen status readouts and cursor measurements. |
