M8190A User’s Guide 19
With this option the number of channels is selected. The M8190A is available as a one
channel (-001) or 2 channel (-002) instrument. There is no upgrade possible from
option -001 to option -002.
These options define the resolution and the maximum sample rate of the M8190A:
-12G : The High Speed Mode offers a maximum sample frequency of
12 GSa/s and a DAC resolution of 12 bits
-14B : The High Precision Mode offers a maximum sample frequency of
8 GSa/s and a DAC resolution of 14 bits
Every M8190A with option -001 or -002 must have minimum one of the two option (-
12G or -14B). Both options can be installed in parallel on the M8190A. If both options
are installed, it is possible to switch between the 12 bit and 14 bit mode by software
configuration. Also, a software upgrade for the options is possible.
This option enables two additional output amplifiers. This gives a total of three
selectable output paths.
1. Direct Output: Optimized for optimum Spurious Free Dynamic Range (SFDR),
Harmonic Distortions (HD)
2. DC Output: Optimized for Serial Data Applications. This amplifier offers up to 1V
amplitude, a voltage window of -1 V to +3.3 V and an external termination voltage
window of -1 V to +3.3 V.
3. AC Output: Optimized for RF applications. This amplifier offers up to 2 V
amplitude, 5 GHz bandwidth, flatness correction – including sinx/x compensation
at 12 GSa/s.
Refer to the data sheet for detailed specification.
Without -AMP, the M8190A offers a Direct Output path.
Option -AMP is software upgradeable.
This option offers 2048 MSa waveform memory per channel with Option -12G, 1,536
MSa with Option -14B and 768 MSa IQ sample pairs with Option -DUC.
Without -02G, the M8190A offers 128 MSa waveform memory per channel with Option
-12G and Option -14B and 64 MSa IQ sample pairs with
Option -DUC.
Option -02G is software upgradeable.
This option offers extensive sequencing capabilities. For more details, refer to the
chapter Sequencing.
Option -SEQ is software upgradeable.
This option provides 15 bit wide IQ sample data at a low speed, which is interpolated to
the sample rate of the instrument and digitally up-converted to a carrier frequency
using an IQ Modulator. Parts of the functionality described in the chapter Digital Up-
Conversion uses sophisticated sequencing capability of the M8190A. As a result, the
functionality described in the sections Configuration at Run-Time and Amplitude
Scaling requires:
Option -SEQ. For more details, refer to the chapter Digital Up-Conversion.
Option -DUC is software upgradeable.
