  • Is a 4 port SNA actually Qty 2 2-port VNA boards?

    • Yes,4 port SNAs have 2 RF boards, but one digital board and the LO board.

    2. Are the ports asynchronous?

    Port 1 and 2 share a source and port 3 and 4 share a source. Each source can only work one port at a time. Source 1 and source 2 are independent and can work at the same time, but they are not phase synchronous. All receivers share an LO, so all receivers work synchronously.

    3. What is the amplitude accuracy of the spectrum analyzer mode?

    The amplitude accuracy of the spectrum analysis is the amplitude accuracy of the receiver +-1 dB. Customers can also perform receiver power calibration for higher accuracy.

    ]]>     Spectrum and vector network analyzers like the SIGLENT SSA, SVA, and SNA series products feature very sensitive circuitry that can be easily damaged by electrostatic discharge or ESD. In many cases, ESD events aren’t obvious. It isn’t always a visible/noticeable event like the “wool sock shock” you may have tried as a child. ESD events often go unnoticed.

    ESD events that occur near a sensitive RF circuit can cause:

    • Complete loss of measurement capability. This can be verified visually. There may be no trace changes on the display when a known good signal is delivered to the input, etc..
    • Increased amplitude measurement error. The additional error could cause the readings to be higher or lower than expected.. from 0.1 dB to 10’s of dB.
    • Increased tracking generator/stimulus source error.

    Instrument designers include ESD prevention and protection in their designs, but this can only minimize the risk of damage.

    Here are some steps you can implement to further minimize ESD events when working with sensitive circuitry:

    1. Maintain a relative humidity above 40%. Low humidity increases the likelihood of ESD events.
    2. Short the center pin and outer shield of cables to neutralize any potential differences before connecting the cable to any sensitive input
    3. Use proper ESD protection when working with input connectors or sensitive boards. Basic protection includes using a 1 MOhm resistor-isolated ESD wrist strap and ESD minimized work surfaces.
    4. Always use properly grounded power outlets and power cords

    ]]>     Fuses are a common circuit element and are key to protecting from overvoltage and overcurrent situations that can damage important circuits.
    Fuse markings are typically stamped symbols located on the metal cap of the fuse.
    Here is a helpful guide to common fuse markings used with instrumentation, taking a common fuse type as an example:
    T 6.3A L 250V
    The first letter, “T” in this case, is the fuse acting speed. Fast-acting fuses disconnect the circuit power more quickly than slow-acting.
    The current rating is next. In this case, “6.3A”.
    “L” is the fuse breaking capacity (or short circuit rating) which is defined as the amount of current that will cause the fuse to open if a fault or short circuit occurs. Low indicates very little over-current will cause an open. High capacity rated fuses will not open unless the current from a short circuit or fast event is significantly larger than the rated value of the fuse.
    The maximum voltage rating is listed next, “250 V” in this case.

    Table 1. Fuse Element Speed Markings

    Marking Fuse Element Speed
    FF Very Fast Acting (Flink Flink)
    F Fast Acting (Flink)
    M Medium Acting (Mitteltrage)
    T Slow Acting (Trage)
    TT Very Slow Acting (Trage Trage)

    ]]>     SMA and 3.5 mm RF connectors are very similar and should be mechanically compatible, but do have some electrical differences that may be important for your application.

    For best performance, use SMAs with SMAs and 3.5 mm connectors with 3.5 mm connectors. If you question the connection integrity, you can use connector gages to verify the proper pin and thread locations.

    Proper cleaning of the mating surfaces with a lint-free swab and isopropyl alcohol is recommended as well as using a calibrated torque wrench.

    For proper torque values of SIGLENT calibration kits, see the Mechanical Calibration Kit Datasheet

    SMA connectors, like those shown below, have a plastic or foam insulator around the center conductor:
