Barkirina standard a belaş ji bo fermanên zêdetir ji $9.9
Polîtîkaya vegerê
Tiştên vegerê dê di nav 40 rojan de were qebûl kirin dema ku roja wergirtina malê ye. Tiştên xweser nayên vegerandin an guhertin. Tiştên ku bi karta diyariya elektronîkî hatine kirin tenê dikarin were guhertin; veger nayê sepandin.
Diyariya belaş
Bi xêr hatî Roymall, malpera weya pîşeyî ji bo kirîna diyariyên depoya departmanê ya premium. Em piştgirî û qedirgirîya we bilind dikin û em dixwazin spasiya xwe bi zêdekirina hêvîya kêfê ya kirînên we nîşan bidin. Dema ku hûn li vir dikirin, hûn ne tenê hilberên kalîteya bilind ên ku jiyana we baştir dikin bistînin, lê hûn ê diyariyek belaş a taybetî jî bi her fermanê bistînin. Amade ne ku koleksiyona me vedikin û diyariyên we yên bêkêmasî bibînin? Di navbijartina me ya hilberên depoya departmanê ya premium bigerin, fermanê bidin û paşê li benda diyariya belaş a we ya bi kirîna we re were.
Polîtîkaya barkirinê
Em ê piştî wergirtina fermanên we ji bo şandina tiştan bi xebatê bigirin û pê ewle bin ku ew bi ewlehî têne. Agahiyên şandinê dê di e-nameya weya pejirandinê de were dayîn.Di piraniya rewşan de, ferman di nav 2 rojan de têne sepandin.Di şert û mercên taybetî de, wê wiha dereng bibin: Dema ku hûn fermanê di şemî, yekşem an jî înên giştî de bidin, dê 2 roj dereng bibin.Normal, ew hewce dike 5-7 rojên kar (ji duşemê heta înê) bêyî ku ji hêla derengiya firînê an faktorên din yên hawîrdorê ve were bandor kirin.Ji ber ku karûbara meya şandinê li seranserê cîhanê ye, ji ber vê yekê dema şandinê dê li gor cihê we be, ji ber vê yekê heke hûn li navçeyên dûr an welatan in, hûn hewce ne ku hinekî bisekinin.

Good news:
The unit is working. Controls is rather friendly and intuitive clear. FW ver.4.1. On the whole it conforms to the description.
Bad news:
- Bad packing, inappropriate for post delivery. The unit box looks as if elephants have danced on it.
- Mains cable is with crappy chinese plug, not European standard. No adaptor even included.
- Switching power supply is a total crap. You have to replace it with a classic linear one.
- Dangerous high voltage leakage from PS. The voltage between generator’s ground parts of all BNC and mains earth (or other laboratory equipment ) is 100VAC. You may easy get an electric shock and fry delicate equipment and microchips.
- Sin wave has glitches at the zero crossing point and half way long
- At 20VAC output waveforms are intact below 5MHz, at higher frequencies waveforms are significantly corrupted
- At 24MHz the amplitude significantly decreases
- You can get usable waveforms only below 5Mhz and below 10VAC of output
Conclusion:
A good generator for testing audio and some TV equipment, not suitable for ham radio.

I bought this unit to replace an earlier model. This model has remote facilities which I wanted to use for automatic testing.
These are the problems:
1) The upper frequency limit is 24MHz but you cannot set the frequency directly to more than 9.999999 using the <> buttons and the dial. You have to go to the units MHZ position and just keep turning and you will go over 10MHz. When you do this the 0.01KHz position disappears too. - see photos
2) Related to 1) the display software has a bug in it. If you program 10MHz the last digit (0.01KHz) disappears. You can still set the lowest digit but it does not show. Sometimes you also get the display 999.9999kHzz - clearly a problem. The good news is the actual output seems to be ok.
3) The included disk includes the Host Communication Protocol V1.2 document. Either this is an earlier document or it is incomplete. as:
a) There is no command to set the frequency above 9.99999999. The command size limit for the frequency is 9 characters which means you cannot enter 10MHz or more using the serial command.
b) The specification says that there is are four downloadable 2048 point waveforms. The serial specification does not include the protocol to do this. This is a feature I wanted for my project.
4) The included software is all in Chinese and is useless.
If you only want to use this unit standalone then it is excellent value for money. If you really need to drive this unit using the serial interface then the information is incomplete.

Q:
Can you generate the same type of wave on both channels simultanously? Like sine wave 1 Khz on bith channels at the same time for example?

The utility on the attached disk cannot be run or installed on my own computer (Win. 10). How, where, and from whom can I buy software that allows me to control the generator with the computer?

The DC offset is +- 10v. But what is the minimum and maximum amplitude range in which 10v offset can be achieved? This is a 24MHz generator but no information on DC offset range is given. Only offset value is provided.
