Minimum pulse repetition rate frequency for EMI enabled analyzers

daisy — Thu, 09 Jun 2022 13:44:36 +0000

The EMI toolkit available for many SIGLENT spectrum analyzers, such as the SSA3X, 3X Plus, SVA, and X-R series, feature a Quasi-peak detector that was designed to CISPR-16 specifications, which include pulse repetition rates. The EMI toolkit has been tested with pulse repetition rate minimum of 20 Hz, but has not been tested below this. … Continued

How to protect sensitive RF instrumentation

daisy — Thu, 05 May 2022 19:32:21 +0000

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:

Maintain a relative humidity above 40%. Low humidity increases the likelihood of ESD events.
Short the center pin and outer shield of cables to neutralize any potential differences before connecting the cable to any sensitive input
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.
Always use properly grounded power outlets and power cords

Common Fuse Information

daisy — Wed, 09 Feb 2022 17:28:04 +0000

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)

RoHS compliance

daisy — Tue, 28 Dec 2021 12:42:55 +0000

Many SIGLENT products are RoHS compliant to EU 2015/863. This is also known as RoHS 3

Check the datasheet for the product in question to find more information.

Do your instruments support UDP communications over LAN?

daisy — Thu, 05 Aug 2021 12:29:29 +0000

Not at this time.

Many instruments support communication via sockets (port 5025) and telnet (port 5024) but the port numbers cannot be changed.

If you use VISA, you can implement LAN via TCP/IP, which does not need a port number.

Here is a listing of current SIGLENT instruments with Socket and Telnet Support.

Are SIGLENT products certified by a Nationally Recognized Test Laboratories (NRTL)?

daisy — Fri, 07 May 2021 19:06:01 +0000

Per OSHA, a Nationally Recognized Testing Laboratory (NRTL) is an independent third-part laboratory recognized by the United States Occupational Safety and Health Administration (OSHA) to test and certify products to applicable product safety standards.

Examples of NRTLs include UL, CSA, and TUV.

Many SIGLENT products are TUV certified, which also covers UL and CSA requirements.

To find out if a specific product is TUV certified, you can check the latest on the TUV website:

Can the SSA3000X Plus, SSA3000X-R, or SVA1000X series analyzer automatically measure the quality factory (Q) of a filter?

daisy — Tue, 13 Apr 2021 14:08:58 +0000

Yes.

NOTE: This is not currently available on the SSA3000X series.

The quality factor of a filter is defined as:

Q = Center frequency/Bandwidth

From the SSA3000X Plus, X-R, SVA1000X Series Manual:

You can find the automatic Q measurement in the Measurement function menu.

Press the Maker Fn button > Select N dB BW marker type and set the amplitude level (dB) at which you wish to measure the bandwidth (BW).

The measurements will be shown in the upper left-hand-side as shown below:
