Informationen

The Tektronix 2232 is a combination nonstorage and digital storage portable, dual-channel Oscilloscope with 100 MHz analog bandwidth and up to 100 MS/s digital sampling rate. The vertical channels have calibrated deflection factors from 2 mV to 5 V per division. The Variable VOLTS/DIV gain control increases the deflection factor at least 2.5 to 1 on any VOLTS/DIV setting. Vertical display modes are CH 1, CH 2, and BOTH, with a choice in BOTH of ADD, ALT, or CHOP. A BW LIMIT feature limits the vertical Amplifier system and the A Trigger system to 20 MHz. The horizontal deflection system calibrated A Sweep speeds range from 0.5 s to 50 ns per division; calibrated B Sweep speeds range from 50 ms to 50 ns per division. A X10 MAG control decreases sweep time per division of the A and B Sweeps by a factor of 10. The fastest sweep-speed time of 50 ns per division is extended to 5 ns per division in X10 MAG. The Variable SEC/DIV control may be used to increase the non-store sweep time per division by a factor of up to four times from the calibrated time per division determined by the SEC/DIV switch setting. In STORE Mode, rotating the Variable SEC/DIV control out of the CAL detent position compresses a 4K sample acquisition record into a record of 1K samples (called 4K compress mode). Also in STORE Mode, the A SEC/DIV X10 Multiplier adds calibrated storage time bases of 1, 2, and 5 s per division to the NON STORE A Sweep speed range for low-frequency signal acquisitions. The digital storage and display portion of the 2232 is microprocessor controlled. Selecting the digital storage features is done with a combination of front-panel controls and menu choices. Selected front-panel controls are read by the microprocessor to determine their settings. Those settings are reported to the user in a crt readout display generated for the CH 1 and CH 2 VOLTS/DIV switch, the A and B SEC/DIV switch, the DELAY TIME Position control, the Voltage and Time cursor differences (on STORE Mode displays only), the position of AC-GND-DC switches, and the A Trigger LEVEL voltage level. All the parametric information for the waveform display is therefore visible when a hard copy is made to maintain a permanent record of the display. When in STORE (digital) mode, additional readout information is displayed showing storage acquisition mode, SAVE REF memories, if displayed, SAVE mode, and SWEEP LIMIT, if active. Digital storage maximum sampling rate is 100 megasamples per second with a maximum stored record length per waveform of either 4096 bytes (4K) for single-channel acquisitions or 2048 bytes (2K) for dual-channel acquisitions (ALT or CHOP). In CHOP mode, both channels are sampled simultaneously. The digital storage acquisition system has glitch-catching capabilities for glitch widths as narrow as 10 ns. Up to three waveform sets (CH 1 and/or CH 2) of 1K record length (512 data points each waveform for dual-channel acquisitions) or one waveform set of 4K record length (2K when dual-channel) may be stored in the SAVE REF memories. In either case, previous data is over-written. A saved waveform may be recalled for display and comparison with the current acquisition waveform and any or all of the other saved waveforms. The X10 MAG control is also functional for STORE waveforms and provides for horizontal expansion of 10 times. The CURSOR Control may be used to reposition the display window on X10 expanded STORE waveforms to view the entire acquisition. On stored waveforms (current acquisition and saved displays), voltage and time measurements may be made using CURSORS. The cursors are positioned to the waveform of interest and then to the points of interest in the waveform. The AV and At crt readouts indicate the voltage difference and timing difference between the positions of the cursors on the waveform selected. Horizontal positioning of the 1K display window within a 4K acquisition record is also provided by the CURSOR Positioning control. In this manner, the entire 4K record length may be scrolled through for display on the crt. The displayed 1K window of a 4K record length acquisition waveform is the data stored when using the SAVE REF memory to save 1K waveform data. A 4K record length acquisition may also be compressed to a 1K record length by rotating the variable SEC/DIV control away from the CAL detent position. The complete waveform is then only one display window in length. A 4K compress waveform may be saved in any of the three 1K SAVE REF memories.
