Rohde & schwarz amiq-01,02,03 modulation generator
Hello! For Action is one Rohde&Schwarz AMIQ-01-02-03 Modulation Generator 30 Day Warranty.
Unit installed option 01, 02, 03.
Option R&S AMIQ-B1 allows the R&S AMIQ to be used for BER (bit error rate) measurements. The device under test (DUT) must deliver the data to be tested and the associated clock. If the DUT does not have its own clock, the clock can be generated by the R&S AMIQ and output via one of the four user-programmable marker channels. The built-in BER tester compares the data with the nominal data and calculates the bit error rate. The result of the BER measurement is available via the remote-control interface. Various standard PRBS sequences (PN9, PN15, etc) are used as nominal data. The BER measurement has an integrating function, i.e. at the wrap-around point of a PRBS sequence the bit error measurement is stopped and restarted by a control signal at the restart input without the previous result being cleared. All partial results are added until the predefined total number of data bits or error bits is attained. Irrelevant data sequences (e.g. preambles) are blanked, if necessary, by means of the control signal at the data enable input so that they do not invalidate the BER measurement. The PRBS
sequence and the two control signals (at the marker outputs of the R&S AMIQ) are generated by means of R&S WinIQSIM .
The option R&S AMIQ-B2 enhances the existing I and Q outputs by providing the inverted I and Q signal outputs. To meet all requirements, the option R&S AMIQ-B2 allows a DC (bias) voltage to be superimposed on the balanced modulation signal (e.g. for setting the operating
point). This bias voltage can be set separately for the I and Q channels with high resolution. Using the R&S AMIQ-B2, unbalanced signals
can be converted to balanced signals without requiring an external circuit.
The option R&S AMIQ-B3 provides the digital I and Q waveform data for each channel at a 68-pin SCSI connector on the front panel. A esolution from 8 bits to 16 bits can be selected for the output signals. So it is possible, for example, to drive digital/analog converters (DACs)
with different word lengths. By matching the word length, clock and level of the output data to the requirements of the DUT, the R&S AMIQ provides TTL-similar digital signals that are optimally suited for testing digital modules.
The I/Q Modulation Generator AMIQ and the Simulation Software WinIQSIMT open up new dimensions for the generation of I/Q signals. The AMIQ is a dual-channel modulation generator that has consequently been designed for use as an I/Q source. It is programmed and set with the Software WinIQSIMT. The AMIQ outputs I/Q baseband signals or even can generate an IF signal (up to 25 MHz).
Each channel can store 4 000 000 samples. Even at high symbol rates sequences of sufficient length can thus be generated. With clock frequencies of up to 100 Msample/s and a high amplitude resolution of 14 bits (16 bits resolution with digital output, option AMIQ-B3), AMIQ is the ideal source for any signal in the world of digital modulation.
An automatic amplitude/offset alignment as well as fine adjustment of the skew provide excellent symmetry of the two channels which previously was extremely difficult to attain with dual-channel ARB generators. The error vector can thus be minimised. A typical application of AMIQ and WinIQSIMT is not only to drive the I/Q inputs of a vector signal generator but also for baseband applications, e.g. for testing I/Q modulators/demodulators.
