AD-M2KBNC-EBZ

ADALM2000 BNC Adapter Board

The AD-M2KBNC-EBZ is an ADALM2000 add-on board which allows the user to connect oscilloscope probes and other test leads to the analog inputs of M2K.

Features

• AC or DC coupling on all channels

• Possibility to reconfigure the analog inputs as differential input channels

• Access to all other ADALM2000 output pins

• Oscilloscope probes, BNC to grabber cables and mini grabber test clips are included in the package

Description

The AD-M2KBNC-EBZ has 2 single ended input channels and 2 single ended output channels. All these channels are terminated in a right-angle BNC connector which provides quick connection and a locking mechanism. The single ended input channels can be reconfigured as differential input channels by modifying a solder jumper on the bottom of the board. In this way, all 4 BNC connectors will be used for the analog input section and the output of the M2K is still available on the 30-pin header of the board.

Applications

• Electronic test and measurement equipment

• General-purpose signal processing applications

• Automated test equipment

• Educational applications

Package contents

• AD-M2KBNC-EBZ

• 2x Oscilloscope Probes (PA360 60MHz x1 & x10 Passive Probe)

• 2x BNC to grabber cables

• 10x mini grabber test clips

Getting Started

The BNC adapter board is simply plugged into the ADALM2000 and can be used straight away. It does not need any supply or additional circuitry.

AC/DC Coupling

Figure 4. AD-M2KBNC-EBZ jumpers for AC/DC coupling

The input and output channels of this board can be AC or DC coupled using the shunt jumpers. In the following table is presented the jumper configuration:

Jumper	Missing	Jumper 1-2 shorted	Jumper 2-3 shorted
S1- Analog In channel 1	inoperable /disconnected	DC coupled	AC Coupled
S2- Analog In channel 2	inoperable /disconnected	DC coupled	AC Coupled
P4- Analog Out channel 1	inoperable /disconnected	DC coupled	AC Coupled
P5- Analog Out channel 2	inoperable /disconnected	DC coupled	AC Coupled

Differential Inputs

The AD-M2KBNC-EBZ inputs are reconfigurable. By default 1+ and 2+ channels are referenced to the GND of the board and are single ended input channels. There are some solder jumpers on the bottom of the board that allow the user to change the default configuration and use the differential inputs, as ADALM2000 allows this. If the jumpers are soldered as in the table below, the BNC connectors J3 and J4 correspond to channels 1- and 2- of the ADALM2000.

Solder jumpers Shorted Pins				BNC Connector to M2K Pin Correspondence
JP1	JP2	JP3	JP4	J1	J2	J3	J4
1 2	1 2	1 2	1 2	1+	2+	W1	W2
2 3	2 3	2 3	2 3	1+	2+	1-	2-
