Horizontal time base designed for use with the 7104 Mainframe to provide optimum bandwidth/ sweep-speed compatibility, but may also be used with the 7700, 7800, and 7900 Series Mainframes. Features: 0.2 ns/div to 0.5/div Calibrated Time Bases. Triggering to 1 GHz. Variable Trigger Holdoff. Peak-to-Peak Auto Triggering. Sweep Rates - 0.2 s/div to 2 ns /div in 25 steps. 10X MAGNIFIER extends fastest calibrated sweep rate to 0.2 ns/div. The uncalibrated VARIABLE is continuous to at least 2.5 times the calibrated sweep. Trace Separation Range - Funclional only in Delta Delay Time mode when alternating or chopping between time-base units. The second delayed sweep display can be vertically positioned at least 3 div below the first delayed sweep display. Delay Time Range - 0.2 or less to at least 9.0 times TIME/ DIV setting. Jitter - 0.02% of TIME/ DIV setting up through 50 us/ div. 0.03% of TIME/ DIV setting plus 0.1 ns for sweep speeds of 20 us/div through 100 ns /div. External Trigger Input - Max input voltage is 250 V (dc + peak ac) for 1 M-Ohm input 1 W average for 50 ohm input. Input R and C for 1 M-Ohm Input is 1 M-Ohm within 5%, 20 pf within 10%; for 50 ohm input, 50 ohm within 2%. Level range is at least ± 3.5 V in EXT + 1.
