6.4.2 Time source information

- Currently measured offset:

- Last time received DCF:

- Sec. counter DCF:

- Last time received link:

- Sec. counter link:

- NTP – Source:

- NTP source offset:

- NTP source jitter:

- NTP source stratum:

last measured offset with source info and type of measurement (only needed for Moser-Baer support).

last time received from DCF source

In (): Information about number of available satellites (only for GPS 4500 and GNSS 3000).

For DCF, this value is random.

the counter is incremented by 1 with each DCF pulse. For the minute marker, the counter is set to 0. last time received from DTS Link analogue sec. counter DCF

current time source (system-peer) of the NTP

Configuring the DTS 4148 through various submenus:

1. Configuring the lines / outputs (DCF/pulse/frequency, serial interfaces,

IRIG/AFNOR/DCF-FSK, SINEC and NTP slave clock line) See chapter "6.5.1

Lines"

2. Configuring the time source, time-keeping etc.

See chapter "6.5.8 Time "

3. Alarm settings (alarm relay, e-mail, SNMP)

See chapter "6.5.15 Alarm"

4. General settings of the DTS 4148 (language, time zone for alarms and display, password for menu, power supply monitoring...)

See chapter "6.5.21 General settings"

See chapter "6.5.22 Network"

6. Services (switching network services such as FTP, Telnet, SSH on or off)

See chapter "6.5.23 Services (network services FTP, telnet, SSH...)"

7. SNMP Configuration for GET/PUT.

See chapter "6.5.24 SNMP" (Traps are dealt with in menu ’2. Configuration’ ’3.

Alarms’  ’3. Traps’. See also chapter “6.5.19 SNMP traps“)

6.5.1 Lines

Under lines, settings can be undertaken for the following functions:

1 DCF - Output

2 DCF / Pulse / Frequency output

 see chapter 6.5.2

 see chapter 6.5.3

 see chapter 6.5.4

4 IRIG / AFNOR / DCF-FSK output  see chapter 6.5.5

5 NTP slave clocks / time zone server  see chapter 6.5.6

6 SINEC  see chapter 6.5.7

6.5.2 DCF – output

The DTS 4148 is equipped with one DCF output line.

This line is available on the electrical current loop DCF output.

1.

Select line function: off or DCF on

2. Select time zone  see chapter 6.5.27 Time zone selection.

6.5.3 DCF / Pulse / Frequency output

© MOBATIME

1. Select line function: Line switched off, line DCF output, line pulse output, line frequency output

2. Select time zone  see chapter 6.5.27 Time zone selection.

3. Select pulse mode: every second, minute, hour or user-defined.

(Only active with the pulse output function)

4. Select pulse length in ms (1-500ms)

(Only active with the pulse output function)

5. User-defined pulse interval (1-3600 sec) only active with pulse type 3 (=user) (the value is also only then displayed). The pulse always occurs after a multiple of the pulse interval from the 0 second in the 0 minute, e.g.:

– Pulse interval 960 sec. (16 min.)

 Pulse occurs: 00:00:00, 00:16:00, 00:32:00, 00:48:00, 01:00:00, 01:16:00 ...

– Pulse interval 25sec

 Pulse occurs: 00:00:00, 00:00:25, 00:00:50, 00:01:15, 00:01:40, 00:02:05 ...

... 00:59:35, 01:00:00, 01:00:25 ...

6. Output correction (-500ms...+500ms)

7. Frequency 1Hz…5MHz

Important:

Important:

Only frequencies which fulfill the following requirements are to be used, otherwise, phase shifts occur:

20'000'000 / frequency = whole number value

Frequencies above 2 MHz are not sent out as a square-wave signal anymore.
