E8257D scpi命令无法识别

大家好。
最近我一直在编程E8257D合成器。
我正在尝试使用“freq:fix xghz”命令设置固定频率,使用“x”设置频率。
我收到“数据超出范围”错误。
该命令通常在以前工作,但现在不起作用。
几个月前修复了合成器,现在它有最新的固件(c.06.16)。
我们在2006年买了它,可能固件没有升级到今年。
可能是固件问题呢?
会建议返回以前的固件吗?
我正在使用与之前相同的设置(当它工作时),使用gpib-u***接口。
谢谢你的帮助。

  Hi all. Lately i have been programing the E8257D synthetizer. I'm  trying to set a fixed frequency with the "freq:fix xghz" command, with "x" the frequency to set. I get a "data out of range" error. The command usually worked before, but now isn't working.  

The synthetizer was repaired a few months ago, and now it has the latest firmware(c.06.16). We bought it about 2006 and probably  the firmware wasn't upgraded up to this year. Could be a firmware problem then? Would be recommended to return to previous firmware? I'm using the same setup as before (when it was working), witht gpib-u*** interface.

Thanks for any help.

嗨 - 我们尝试了命令,它工作正常。
输入的频率可能超出单位范围。
:FREQuency:FIXed支持所有模型[:SOURce]:FREQuency:FIXed | UP | DOWN [:SOURce]:FREQuency:FIXed?
此命令设置信号发生器输出频率,或增加或减少当前RF频率设置。
频率值。
UP通过第125页上的:FREQuency [:CW]:STEP [:INCRement]命令设置的值增加当前频率设置。前面板向上箭头键执行相同的功能。
DOWN通过第125页上的:FREQuency [:CW]:STEP [:INCRement]命令设置的值减小当前频率设置。前面板向下箭头键执行相同的功能。
要设置频率模式,请参见“:FREQuency:MODE”(第119页)。有关信号发生器频率和功率规格的列表,请参阅第153页上的“[:LEVel] [:IMMediate] [:AMPLitude]”。示例:
FREQ:FIX 10GHZ前面的例子将信号发生器频率设置为10 GHz。

  Hi -

We tried the command and it works fine. It is possible the entered frequency is exceeding the range on unit.

:FREQuency:FIXed
Supported All Models
[:SOURce]:FREQuency:FIXed |UP|DOWN
[:SOURce]:FREQuency:FIXed?
This command sets the signal generator output frequency , or increments or decrements the current
RF frequency setting.  A frequency value.
UP Increases the current frequency setting by the value set with the
:FREQuency[:CW]:STEP[:INCRement] command found on page 125. The front panel
up arrow key performs the same function.
DOWN Decreases the current frequency setting by the value set with the
:FREQuency[:CW]:STEP[:INCRement] command found on page 125. The front panel
down arrow key performs the same function.
To set the frequency mode, see “:FREQuency:MODE” on page 119. For a listing of signal generator
frequency and power specifications, refer to “[:LEVel][:IMMediate][:AMPLitude]” on page 153.
Example
:FREQ:FIX 10GHZ
The preceding example sets the signal generator frequency to 10 GHz.
