set_frontend

Configure the Analog front-end settings of the Moku when in Multi-Instrument Mode.

When in Multi-Instrument Mode, the instruments themselves cannot configure the front-end settings of the Moku. For example, the Oscilloscope instrument is no longer in control of the input attenuation/range, as that input may be shared by multiple instruments.

When in Multi-Instrument Mode, the user must use this set_frontend function rather than the ones "typically" found in the namespaces of individual instruments.

Bandwidth

Setting the bandwidth explicitly is only available on Moku:Pro and Moku:Delta. For Moku:Delta, the bandwidth can be set with the bandwidth or impedance parameters. Set the bandwidth to 2 GHz or 6 GHz bandwidth with 50 Ohm impedance, or set the impedance to 1 MOhm to set the bandwidth to 1 MHz.

Read about how to select bandwidth, range, gain and attenuation for your application.

Moku:Delta 6 GHz mode

Moku:Delta's 6 GHz analog input bandwidth, with 5 GSa/s sampling. Signals above 2.5 GHz will alias back into the first Nyquist zone (DC - 2 GHz).

Make Connections First

You must connect an Input (i.e. ADC) to an instrument before configuring its settings. See set_connections for details of making the connection.
