B&K Precision Digital Oscilloscope 2520

The 2520 is a 20 MHz, 2 channel digital oscilloscope from BK Precision. Measure voltage or current signals over time in an electronic circuit or component to display amplitude, frequency and rise times, etc. Applications include troubleshooting, production test, and design. Additional Features: Bandwidth: 20 MHz Number of Channels: 2 Memory: 1024 x 8 bit Sample Rate: 2 MS/s Vertical Resolution: 1 in 256, approximately 30 steps/div Allows repetitive waveforms of up to 20 MHz to be digitized and stored Vertical Amplifiers Sensitivity: 2 mV/div to 10V/div in 1-2-5 sequence with vernier control providing continuous adjustment between steps Accuracy: ±3% Input Resistance: 1 Mω Input Capacitance: 28 pF Frequency Response: DC: DC to 20 MHz (-3dB); AC: 2 Hz to 20 MHz (-3dB) Rise Time: 17.5 ns Analog Operating Modes: CH 1=X Axis, CH 2= Y Axis, CH 1: CH 1, single trace; CH 2, single trace; Dual: CH 1 and CH 2, dual trace. Alternate sweep operation (alternates between channel 1 and channel 2 signal) when sweep speeds of 0.2 ms/div or faster are selected. Chop sweep mode (both channels displayed simultaneously) when sweep speeds slower than 0.2 ms/div are selected Chop Frequency: Approximately 500 kHz Polarity Reversal: CH 2 only Maximum Input Voltage: 400 V (dc + ac peak) or 800 V ac p-p Sweep System Analog Sweep Speed (Norm mode): 0.5 µs/div to 0.2 s/div in 1-2-5 sequence, 18 steps. Vernier control provides fully adjustable sweep time between steps Digitizing Sweep Speed (Store mode): 0.5 µs/div to 50 sec/div, 25 ranges in 1-2-5 sequence Accuracy: ±3% (to 0.2 µs/div) Sweep Magnification: 10 X, ±3% (increases maximum sweep speed to 50 ns/div ±5%) Triggering Modes: Auto (free run) or Normal Source: CH 1, CH 2, or External Coupling AC: 4 Hz to 20 MHz DC: DC to 20 MHz TV: Trigger signal is routed through a sync separator. Horizontal sync pulses are selected at sweep times of 0.05 ms/div and faster (TV Line). Vertical sync pulses are selected at sweep times of 0.1 ms/div and slower (TV Frame) Level: ± 90°: permits selection of triggering at any point on the positive and negative slope of the displayed waveform Slopes: ± The Bk Precision 2520 is a 2 Channel, 20 MHz Digital Storage Oscilloscope. The 2520 has a rectangular CRT with a large 8 x 10 centimeter viewing area. Internal 8 x 10 division graticule eliminates parallax error. The Model 2520 has two vertical input channels for displaying two waveforms simultaneously. Selectable single trace (either CH 1 or CH 2) or dual trace for both analog and digital operating modes.
