We have recently polled a number of our customers about the printed manuals that we supply with our clocks.

We will therefore shortly be discontinuing supplying printed versions of the manuals and replacing them with printed Quickstart Guides. The full manual

I know that there's a bit of a stretch between GPS clocks and GPS location devices, but a recent news story really tickled my fancy.

We recently had an example of how our system of activating NTP and PTP through the use of a license key can be a great help to our customers. A customer ordered a number of TTM 01-E clocks. But after the clocks were shipped they realised they had a need for NTP (they wanted to synchronise a number of computers). With low expectations, they contacted us to see what could be done.

Many modern power systems are designed to include redundancy; this can be on varying levels, depending on the policy of each Utility. The most common forms of time synchronisation redundancy range from redundant power supplies, to complete duplicate clock systems, through to use of dual IRIG-B or Ethernet rings. We can accommodate any of the above. One example is illustrated by the attached PDF,

Every now and then we get a support query from a customer who is experiencing problems with poor  satellite reception. Usually the answer to this is straightforward - the antenna is being blocked. The ideal GPS antenna installation is on the roof of a building with a clear line of site of the whole sky. If the antenna is being masked by another object you are likely to get poor reception. If

We are currently working on developing timing devices for femtocells and picocells. Femtocells and picocells are small telecommunications base stations for mobile phones. They require a high level of precision, which is where we come in. If you are involved in a femtocell and picocell project and require accurate timing send us an email. It would be great to talk with you.

We have recently signed an OEM agreement with a European developer of data communication products. They will be reselling Tekron clocks under their own name. OEM arrangements like this are very much mutually beneficial. It allows us to enter markets in which we otherwise would have difficulty getting into and gives the OEM partner a range of high quality clocks without having to go through many

A long term TCG 01 user recently approached us about our new TCG 02-E. The TCG 01-E was ideal for their needs, however they liked the dual power supply option in the TCG 02-E. But the problem was they did not need all the additional outputs that the TCG 02-E offers.So - would we consider offering the TCG 02-E with the same number of outputs as the TCG 01-E?The simple answer is yes.In the coming

Following on from our last post about running two clocks from the one antenna...One of our partners has suggested another way of doing this without the need for a splitter - slaving one clock off another.With this approach, you will connect the first clock directly to the antenna, then slave a second clock off the first via an IRIG-B connection. This is the approach they took with one of their

The simple answer is yes; but as to be expected, there are potential issues that need to be considered:Should the antenna go down for any reason (e.g. lightning strike) you will lose time signals from both clocksYou will need to purchase an antenna cable splitter (aprox. US$350)We recommend that you use an active antenna splitter, which will need to be powered. If you choose to use a passive

They are very similar (5x10E8). However the XO can only maintain this over a minimal temperature range (0.5degC) centred on the temperature that the unit was operating at when it switched over to free run after having been sync'ed to GPS. The temperature-compensated device maintains this over a wider temperature range - typically +|- 10degC, also centred around the temperature of the device at

1. The PC which you are using to configure the TTM 01-E is not connected to the same sub-net2. The PC is blocking the executable file.

1. The Impedance of the clock is not matched to the impedance of the Load. Generally a Terminating resistor of between 100 and 150 ohms is required at the end of the line to prevent signal reflection.2. One or more connectors may not be terminated correctly, creating a short.3. The cable and connector impedance is not matched, causing signal reflection.4. The clock is not connected to a GPS

GeneralThe RS422 and RS485 standards both describe a very similar form of signalling designed primarily for use on twisted pair cables. The standards describe the physical nature of the signals and the ways in which they can be switched.The main difference between the two standards is that RS422 is designed for point to point one way signalling from one device to one or many devices, whereas the

There was recently some confusion about the specifications for the RS232 ports on our clocks. Hopefully the post below should give a good explanation. Please don't hesitate to post a comment if you have any questions.The RS232 ports on Tekron TCG01 and TCG08 clocks are implemented in the following way:-1. The port is physically implemented in a DCE configuration. This has been done so that a

Sub-microsecond accuracy is an essential requirement in sub-stations that are deploying protection systems using Synchro-phasor technology. Even if a currently equipped substation does NOT use synchro-phasor technology, there is a high likelihood that this will become necessary over the next few years. Accordingly, it is wise to equip the time sync system to support microsecond accuracy.This can

We recently received a question asking the differences between version 1 and version 2 of IEEE 1588.V1 (2002) does not support transparent clocks or profiles. Version 1 IEEE 1588 packets are larger, making more traffic. V1 is now completely redundant and is obsolete.V2 (2008) allows for transparent clocks (including End-to-End and Peer-to-Peer delay options) and industry profiles, and has smaller

Since early 2009 all our GPS products containing the Time Server function have been shipped with our own 100mbs time server modules installed.The new module offers dramatically improved performance over the earlier, third-party sourced module, which only operated at 10mbs and had accuracy of around 1ms (millisecond).The new time server modules that are now being fitted in our TCG01 and NTS01

The short answer: about 100, but lots more if Peer-to-Peer delay mechanism is used on the network.The long answer:The maximum number of PTP packets per second that the TTM 01-E can handle is approximately 300. The TTM 01-E operates according to the default PTP V2 profile, supporting multicast operation and user-selectable End-to-End or Peer-to-Peer Delay mechanism.Assuming that the TTM 01-E

Tekron clocks will synchronize many IEDs in parallel from the one TTL output. The number of devices that can be synchronized depends primarily on the impedance of each device being synchronized.We have written a guide to enable you to validate whether the number of IEDs that you are planning on synchronizing can be supported by your Tekron clock.You can download the guide from here.

The following points were made recently by Brian Smellie, Tekron’s founder and Technical Director. Brian was responding to a query from one of our partners on the merits of the DCF-77 time code as compared with IRIG-B.DCF-77 and IRIG-B are both serial time codes; but DCF-77 transmits one code frame every minute, whereas IRIG-B transmits one code frame every second.DCF-77 is a "Future Reporting"

NTP - Network Time ProtocolWe quite often get asked this one. The “S” in SNTP stands for “simple”. In a nutshell, SNTP is a much simplified sub-set of the full NTP protocol, and requires dramatically less processing resource to implement. The two versions of the protocol are designed to inter-operate happily together. SNTP is by far the most common form of the protocol used in client

A question was recently asked on this blog whether there are any disadvantages in using an up/down converter in situations where long cable runs are required, such as when the clock is used at the bottom of a tall building or big power plant.The antenna cable we normally supply with our clocks is LMR240UF. This is very good cable, but is limited to runs of 60m or less. For runs between 60m and

A customer recently asked whether they can use an indoor antenna located near a window with our clocks. The antenna they had in mind was “a standard GPS 12V L1, 1575MHz Antenna”. Our answer to this question is below.The voltage supplied by our equipment to power attached antenna is 5V not 12V, so an antenna which expects a 12V supply will not work at all. Having said that, customers can mount a
