The module calibrates at the current frequency, or at a range of frequencies, and stores the results so that if you change frequency and return again, the calibration still applies.
  • Page 25 MENU BAR ON SOFT FRONT PANEL IQ Calibration Differential IQ: there are two differential IQ calibrations: Cal Outputs is used to null out any DC offset on the differential outputs. Cal Inputs is used to null out DC offsets on the analog IQ input path. If you apply no signal, this cal nulls DC offsets internal to the module’s analog IQ input path.

  • Page 47: Appendix A Format Of Arb Files

    Appendix A Format of ARB files General The ARB stores digital representations of waveforms. Any number of waveforms can be stored, up to a total capacity of 32 Msamples. The memory used is volatile. Each waveform consists of two components, I and Q. When the ARB is enabled and one of the waveforms selected, it is converted into a pair of analog signals that can be used to drive the I and Q channels of the RF modulator, or output as analog baseband IQ when Option 01 is fitted.
  • Page 48 FORMAT OF ARB FILES When the above waveform is selected and played, it is read out of the memory at 4.9152 Msample/s. The ARB interpolates this data stream so that it has a data rate of 58.9824 Msample/s. The data is written to the two 14-bit D-A converters at 58.9824 Msample/s. The analog outputs from the D-A converters are then filtered to remove switching and quantization noise and high-frequency images.

  • Page 53 DATA CONNECTOR AND TIMING LVDS data used as IQ input Data is supplied to the LVDS interface using a 16-bit bus. The D/A converters are 14 bits and by default the module uses bits [15:2]; however, it is possible to select to use [13:0] instead. Similarly, data is signed two’s complement by default, but it is possible to select unsigned instead.

  • Page 55: Chapter 4 Brief Technical Description

    Chapter 4 BRIEF TECHNICAL DESCRIPTION Introduction The 3020A is a digital RF signal generator PXI module. It contains dividers to give a frequency range of 250 MHz to 2.7 GHz, IQ modulators, leveling control, step attenuation to −120 dBm, and a dual-channel arbitrary waveform generator. It does not contain a local oscillator (LO).
  • Page 56 The highest order of interpolation is 3072, which means the lowest sample rate is 14.323 kHz. These filters are used on both ARB and LVDS data. The 3020A applies all corrections to IQ data in the digital domain. This includes DC offset, gain imbalance and phase skew between I and Q.
  • Page 57 BRIEF TECHNICAL DESCRIPTION The leveling loop derives its error signal by comparing the input to the comparator from the RF detector ADC, and the wanted IQ power. The IQ power is converted to detector volts in a look-up table. During bursted IQ data, the loop can be frozen while ramping IQ data up or down, and can also switch off the signal between bursts, improving on-off ratio.
  • Page 58 BRIEF TECHNICAL DESCRIPTION The detector output is amplified and buffered before being fed back to the logic board for A-D conversion. A temperature-sensing mode is provided, where the detector is disabled and the output replicates the voltage. This can be measured and used to periodically adjust calibration in accordance with temperature and stored data.
  • Page 59 BRIEF TECHNICAL DESCRIPTION In differential output mode, I and Q outputs from the logic and control board are buffered and pass through variable attenuators that provide up to 22.5 dB attenuation in 1.5 dB steps. They are then amplified by switched gain power stages, formed of paralleled amplifiers in order to provide low noise.

Follow the instructions provided in the 3000 Series Common Installation Guide (part no. 46882/663) to ensure that this software is correctly installed.
