Holding Informtest announces new digital oscilloscope module MOSC-6

10/06/2011

M-module MOSC6’s intended to work as digital oscilloscope or fast digitizer in informational measuring systems based on two different measuring platforms: VXI bus and LXI. M-module is implemented as a mezzanine of triple width that can be installed onto mezzanine carriers for VXI (NM-VXI) and LXI (Mezabox-1, Mezabox-2), which connects to it, via Local informational bus.

M-module has two measuring channels. Each measuring channel can perform measurements of input signal with maximum span from -50 V to 50 V. The entire span is divided into 11 sub-ranges from ± 25 mV to ± 50 V. Vertical resolution in each range is 8 bit. Minimal period of discreetness for each measuring channel is 200 ps, which is equal to maximum sampling frequency of 5 GHz. The module has a control over setting of a discreet period. Full sweep is determined by sampling period and maximum size of RAM, which is 1024 Mb (1024M counts) per channel.

The bandwidth of a measuring channel – not less than 900 MHz. The module has a function of limiting the bandwidth with a controllable analog Low- Pass Filter with cut-off frequencies 300 MHz and 20 MHz. The filter is turned on/off through the software control panel.

The module has a synchronization channel intended for synchronization of oscilloscope’s performance from external trigger signal. Maximum span of an input signal is from -5V to 5V. Level of synchronization is set through software. For simultaneous work of a number of MOSC-6 modules, included into a system, there is a dedicated SMB connector on a front panel, through which the module can send a trigger signal.

There is an option for the MOSC-6 to operate from external 10 MHz clock frequency generator, which is converted by the module into a clock frequency of 2.5 GHz. It’s necessary for simultaneous synchronization of a number of oscilloscopes from a one generator. One of the oscilloscopes can take on a role of the generator. For synchronization there are two separate SMB-connectors on a front panel: one for input frequency, and one for output. There’s also an internal generator of calibrating signals that allows performing calibration and self-test of the module.

The module has an option (controlled through the software) of setting a DC input to open or closed mode.

Maximum RAM size is 1024 Ms readings per each measuring input.

An option to set programmable limit to the amount of logged in a single measurement data from 1K up to max. with a step of 1 K.

Triggering sources:

- Program (Software)
- Internal – from any input (by a threshold of a trigger signal);
- From external signal;
- From TTL line;

Triggering parameters:

- Waiting/auto modes, synchronization from front or from cut, by parameter of a window, pulse width, by a quantity of starting events;
- Setting a number of fixed readings before synchronization (varying in a range from 16 to N-16 with a step of 16, where N –length of a sweep in readings).
