for sale.
200 MHz Digital Storage Oscilloscope, Two Channel. Sample Rate on Each Channel: 2.0 GS/s. Maximum Record Length: 2.5K points. Vertical Resolution: 8–bits. Vertical Sensitivity: 2 mV to 5 V/div. Vertical Accuracy: ±3%. Max Input Voltage: 300 VRMS CAT II; derated at 20 dB/decade above 100 kHz to 13 Vpk-pk AC at 3 MHz and above. Position Range 2 mV to 200 mV/div ±2 V; >200 mV to 5 V/div ±50 V. Bandwidth Limit: 20 MHz. Input Coupling: AC, DC, GND. Input Impedance Selections: 1 megaohm in parallel with 20 pF. Time Base Range: 2.5 ns - 50 s/div. Accuracy: 50 ppm. Acquisition Modes; Peak Detect – High frequency and random glitch capture. Captures glitches as narrow as 12 ns (typical) using acquisition hardware at all time/div settings from 5 µs/div to 50 s/div. Sample – Sample data only. Average – Waveform averaged, selectable: 4, 16, 64, 128. Single Sequence – Use the Single Sequence button to capture a single triggered acquisition sequence at a time. Trigger Modes – Auto, Normal, Single Sequence. Trigger Types; Edge (rising or falling) – Conventional level-driven trigger. Positive or negative slope on any channel. Coupling selections: AC, DC, Noise Reject, HF Reject, LF Reject. Video – Trigger on all lines or individual line, odd/even or all fields from composite video or broadcast standards (NTSC, PAL, SECAM). Pulse Width (or Glitch) – Trigger on a pulse width less than, greater than, equal to, or not equal to a selectable time limit ranging from 33 ns to 10 s. Trigger Source: CH1, CH2, CH3, CH4, Ext, Ext/5, AC Line.. 1/4 VGA, passive color LCD with color on black background with adjustable multi-level contrast.
