    Help Menu To view information about the 7000 Series GUI itself, the help menu can be used. It also offers the possibility to log a session or some interaction in an encrypted way for support purposes. Activating this option will slow down performance significantly so it is only advised to so when instructed by Berkeley Nucleonics support staff.

  • Page 23: Mode: Absolute Phase Noise Measurement

    Spectrum Analysis Clicking on a tab will activate the corresponding measurement setup. The following sections describe each measurement mode and how to configure the 7000 Series to successfully perform a measurement. Mode: Absolute Phase Noise Measurement Use this tab to measure absolute phase noise of a continuous waveform (CW) or a pulse modulated signal.

  • Page 24: Absolute Phase Noise Measurement Of A Continuous Wave (Cw) Signal

    After clicking on the Measure button, the phase noise measurement is initialized. A couple of calibration steps are automatically performed, and phase noise data is acquired from the 7000 Series. Figure 7 shows the GUI during the measurement process. The measurement trace is displayed in red, detected spurs are marked black.

  • Page 25: Absolute Phase Noise Of A Pulsed Signal [Requires Option Pulse]

    Absolute Phase Noise of a Pulsed Signal [requires Option PULSE] The 7000 Series can be configured for pulsed signal measurements by activating the pulsed mode checkbox in the Signal Detection area. The 7000 Series will automatically detect all the necessary parameters such as pulse rate and duty cycle and adjust the measurement process accordingly.

  • Page 26: The Plot Window Tabs

    Figure 8 Absolute phase noise measurement of a pulsed signal. The Plot Window Tabs The plot window is comprised of six tabs: Measurement, Time Domain, Data Table, Statistics, DUT Info, and Measurement Status: Measurement is the main tab to display frequency domain results like phase noise plots. Time Domain provides time domain measurement information during idle state (frequency and power detection, calibration), and during the measurement process (locking, and data acquisition).

  • Page 27: List Of Traces

    Figure 9 The Statistics tab provides additional information about the selected data trace DUT Info constantly monitors the DUT CW frequency and power while in idle mode and shows the tuning voltage of internal references during the measurement process. The values are updated approximately once per second, while in GUI idle state.

    Add: The current measurement trace (red trace) can be stored in the trace list by clicking on the “add” button. The stored trace is named with “trace <i>” (where <i> is the smallest number not already taken by another trace). Additional information, such as DUT frequency, number of correlations, and time and date of measurement are included in the trace list.

    7000 Series: All traces in an internal format; the internal file format can be loaded back into the GUI Traces can be imported if they were previously saved in the 7000 Series internal format. Use the Plot → Load Trace(s) menu or drag the file into the application. Select the 7000 Series file to import and confirm by clicking the Open button.

  • Page 30: Measurement Time (Using Gui)

    Measurement Time (using GUI) The measurement time required by the 7000 Series depends on several parameters. The total measurement time consists of the setup time, sampling time, and post processing time. Setup Time The setup time largely depends on the user settings and reference sources used. Very low noise references tend to have a small tuning sensitivity and bandwidth.

  • Page 31: Additive Phase Noise Measurement

    Additive Phase Noise Measurement The additive phase noise measurement tab provides single channel or two channel cross-correlation additive phase noise measurements. It supports measurements of active or passive, non self-oscillating devices such as amplifiers in linear and non-linear operation or even frequency-translating devices such as mixers, frequency multipliers or dividers.

  • Page 32: Additive Phase Noise Of A Pulsed Signal (With Option Pulse Only)

    Additive Phase Noise of a Pulsed Signal (with Option PULSE only) To configure the 7000 Series for additive pulse modulated signals, activate the pulse option in signal detection. The signal is automatically detected, and duty cycle and pulse repetition frequency are shown (see Figure 12).

  • Page 33: Amplitude Noise Measurement

    The measurement procedure is identical to unmodulated signals. For the pulsed signals, the beat signal will be a flat line when this is achieved. Amplitude Noise Measurement From an interface standpoint, the amplitude measurement tab is equal to the absolute phase noise tab (see section 0).

  • Page 38: Time Stability

    Time Stability The Time Stability mode provides the ability to measure the long-term stability of a CW signal. It measures frequency versus time for long time periods (10 seconds to multiple days) and can derive Allan deviation from the measurement. After starting the measurement, the instrument starts to gather data. After a couple of seconds, the first measurement is shown.

VCO Characterization The VCO characterization tab provides the ability to fully characterize a voltage-controlled oscillator (VCO or VCXO), including Kvco, current draw, power output, pushing and spot phase noise over a specified control voltage range.

  • Page 40: Measurement Procedure

    Measurement Procedure Connect the VCO to the 7000 Series. Use the DC SUPPLY 1 port on the rear panel of the 7000 Series as supply voltage, the DUT TUNE port on the front panel of the 7000 Series as control voltage and connect the RF output of the VCO to the DUT RF IN port of the 7000 Series.
  • Page 41 Remotely Programming the 7000 Series The 7000 Series can be remote controlled via three independents, but functionally equivalent interfaces: USBTMC, LAN, and (optionally) GPIB. Access via LAN The signal analyzer can be remotely programmed via a 10/100/1000Base-T LAN interface and LAN-connected computer using one of several LAN interface protocols.
  • Page 42 The GPIB interface operates with IEEE488.2 and SCPI. The instrument can be controlled by a GPIB external controller. When controlling the 7000 Series using GPIB commands from the external controller connected to the GPIB connector, the talker/listener GPIB address of the 7000 Series requires setting. The default GPIB address of the 7000 Series is 1.
  • Page 43 Maintenance and Warranty Information Adjustments and Calibration To maintain optimum measurement performance, the instrument should be calibrated every 24 months. It is Berkeley Nucleonics recommended that the instrument be returned to or to an authorized calibration facility.
