• Notes
• The 7B50 Time Base unit is recommended for use with the 7400, 7500, 7600 and Storage FAMILIES to provide bandwidth/sweep speed compatibility. However, the 7B50 may be used in any 7000-Series mainframe.
  The 7B50 also has a horizontal amplifier input for uncalibrated X-axis deflection from an external source. The calibrated TIME/DIV range is from 5 ns/div to 5 s/div. The 5 ns/div rate is otained with the X10 MAGNIFIER.
  Triggering control is very flexible with 12 push-button positions to program MODE, method of COUPLING, and SOURCE. For routine applications, hands-off triggering is accomplished by actuating the three upper-most push-button switches: INT SOURCE, AC COUPLING, and P-P AUTO MODE -- the most commonly used combination. The P-P AUTO MODE provides a baseline trace in the absence of a signal and a triggered trace at any position of the LEVEL/SLOPE control when a signal of 0.5 div or greater is present. Except for the selection of + or - SLOPE, this mode is completely automatic. The other triggering positions are useful for specific applications.
  The triggering frequency range is from DC to 100 MHz, selectable within that range by the method of COUPLING. AC LF REJ attenuates undesirable trigger components below 30 kHz (60 Hz would be almost totally rejected); AC HF REJ attenuates high-frequency components (above 50 kHz) which can cause triggering problems during low-frequency applications. SINGLE-SWEEP functions with lighted READY indicators and manual reset are associated with the trigger MODE controls.
