MX-30 Transmitter Input Multiplexor Switch
for Cabled Electrode Arrays

[caption id="attachment_2302" align="alignright" width="150"] MX30 Transmitter Multiplexor[/caption]
An essential component for rapidly acquiring resistivity data using cabled electrode arrays, the MX-30 is a computer-controlled switching interface between a transmitter, a multi-channel receiver (such as the Zonge GDP) and an array of electrodes.  Weight: 16 kg (35 lb).

  • Use an MX-30 multiplexor with a GDP receiver and ZT-30 transmitter to gather Electrical Resistivity Tomography data.
  • Connect transmitter leads to any pair of electrodes, up to 30 electrodes.
  • Select any number of electrode pairs for input to the receiver.
  • Up to 16 output channels, or purchase fewer channels to reduce initial cost and upgrade later in the field.
  • Cascade multiple MX-30s together to address multiple electrode arrays.
  • Control configuration via RS-232C serial communications.
  • Control software available for laptop.
