The storage feature can be used to store single shot occurrences for later viewing or photographing. Comparison of waveforms can be accomplished by storing several separate occurrences and later viewing them simultaneously.
The horizontal amplifier has a direct-coupled bandwidth of dc to 5 MHz. The ac-coupled bandwidth is 5Hz to 5MHz with a dynamic range of +/- 20 volts. The amplifier has front-panel selectable deflection factor ranges of 1 V/div (X1), 0.2 V/div (X5) and 0.1 V/div (X10). A vernier control provides continuous adjustment between ranges. A front panel BNC connector permits the use of external deflection signals. The external input impedance is 1 megohm shunted by approximately 30pF.
A rear-panel BNC connector (Z-axis Input) is provided for external control of CRT blanking. A signal of approximately +2 V, 5 ns pulse width (< 10 MHz) will blank a trace of normal intensity.
Four rear-panel BNC connectors provide recorder outputs for use with spectrum analyzer plug-ins. Since these outputs are dependent upon the plug-ins utilized, the appropriate plug-in Operating and Service Manual should be referred to for identification of the output signals available.
*Note* These outputs should not be used when a standard 1800-series plug-in is installed in the oscilloscope.
A 10 V, 1-kHz square-wave signal is available at the front panel for calibration purposes.
The cathode ray tube has an internal graticule and P31 aluminized phosphor. Variable persistence and storage are provided by internal elements.
The 1805A Dual Trace Amplifier Plug-In is a 100MHz vertical amplifier that provides accurate measurements for both digital and analog design and troubleshooting. A selectable high impedance with low input capacitance or 50 ohms input provides accurate pulse and CW measurements. Other features that provide accurate, convenient measurements are: dual channel, differential Input,flexible triggering, 5 mV/div to 10 V/div deflection factors from DC to 100MHz on all ranges, selectable display polarity on each channel, and up to 200 divisions of offset. Designed for 180-Series Oscilloscope Mainframes.
