# 2520 B&K Precision Digital Oscilloscope Used

**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.
