The DIO port is a VHDCI 68 pin connector as introduced by the SPI-3 document of the SCSI-3 specification. It is a female connector that requires a 32 mm wide male connector. The DIO port features 32 bits that can be configured byte-wise as inputs or outputs.

The figure below shows the architecture of the DIO input/output. The DIO port features 32 bits that can be configured byte-wise as inputs or outputs by means of a drive signal. The digital output data is latched synchronously with the falling edge of the internal clock, which is running at 60 MHz. The internal sampling clock is available at the DOL pin of the DIO connector. Digital input data can either be sampled by the internal clock or by an external clock provided through the CLKI pin. A decimated version of the input clock is used to sample the input data. The Decimation unit counts the clocks to decimation and then latches the input data. The default decimation is 3e6, corresponding to a digital input sampling rate of 20 samples per second.
Performance Diagrams¶
Input noise amplitude depends on several parameters, and in particular on the frequency and on the input range setting. The input noise is lower for smaller input ranges, and it is recommended to use small ranges especially for noise measurements. Figure 3 shows the noise density of the voltage input with DC coupling. The input noise with AC coupling is the same as long as the frequency is higher than the AC cutoff frequency (see Table 8). The noise is independent of the input impedance setting, 50 Ω or 10 MΩ. The corner frequency of the 1/f noise is in the range of 100 Hz and the white-noise floor is typically 2.5 nV/√Hz for the smallest input ranges.
A note on input voltage noise and AC coupling. The input voltage noise will increase at low frequencies, when using AC coupling at the signal input of the MFLI. For example, the input voltage noise of the 10 mV input range is around 10 nV/√Hz at a frequency of 10 Hz, as shown in the figure above. When switching on AC coupling, the noise increases to around 75 nV/√Hz. The reason is that the 10nF AC coupling capacitor has an impedance of 1.6 MΩ at 10 Hz. Together with the 10 MΩ input bias resistor of the MFLI input amplifier, you get the increased noise density. To work around this problem, use DC coupling for the signal input. An external large capacitor may be employed if AC coupling must be used.
Figure 4 shows the noise density of the current input. The frequency range of the measurements for the smaller input ranges is limited by the bandwidth of these ranges as specified in Table 10.
Figure 5 shows the SSB phase noise measured at the signal output. For this measurement, the signal output was connected to a phase noise analyzer and the output amplitude was set to 5 V. The measured phase noise at 5 MHz and 10 kHz offset is around -153 dBc/Hz.
Figure 6 shows the noise density of the voltage output into 50 Ω. For high-impedance loads, the voltage noise levels in the figure need to be doubled. The output noise was measured with no signal and 0 V offset. For the ranges 10 mV and 100 mV, the voltage noise is basically identical with a flat-band noise level of 14.5 nV/vHz at 100 kHz into 50 Ω. For high-impedance loads, the value would be around 29 nV/√Hz. The 10 V range shows the largest noise with 34.5 nV/√Hz at 100 kHz. The corner frequency of the 1/f noise is in the range of 10 to 20 kHz.
