不能更新或刷新PNA上的显示

我正在研究一个不是由我编写的程序和一个较旧的仪器，我已经为PNA更新了它。
我得出的结论是，我看到的一个问题是某些命令有效但在显示屏上没有刷新。
示例：S11与时间的关系显示Y轴从0到0.2单位。
代码有一个条目（当我检查了所有值时）给出：disp：wind1：trace1：Y：pdiv 0.02那应该设置比例以便有10条水平线，对吧？
显示屏显示4条水平线，即0.05 /格。
有趣的是，在左上角，显示屏显示“CH1 S11 linMAG 20mU /”，即它反映了编程的内容，而不是屏幕上显示的内容。
我有一个类似的问题，其中标记的小数位数已设置（也使用DISP：命令），并且语法看起来有效，我已经看到它工作但是当程序运行时，它似乎被忽略
”。
关于发生了什么的任何想法？
有人遇到“刷新屏幕”命令（不是扫描）吗？
不幸的是，我无法正常访问分析仪 - 我正在做我可以在场外和偶尔访问的内容。

  I'm working on a program that was not written by me and for an older instrument and I've updated it for the PNA.  I'm coming to the conclusion that a problem I'm seeing is that some commands are valid but not refreshed on the display.

Example: an S11 vs. time display shows a Y axis from 0 to 0.2 Units.  The code has an entry which ( when I've checked all the values ) gives:

disp:wind1:trace1:Y:pdiv 0.02

That should set the scale so that there are 10 horizontal lines, right?

The display shows 4 horizontal lines i.e. 0.05 /div.  Interestingly though, at the top left the display says "CH1 S11 linMAG 20mU/" i.e. it reflects what was programmed, not what is shown on the screen.

I have a similar problem where the number of decimal places for the markers has been set ( also with a DISP: command ) and again the syntax looks valid and I have seen it work but when the program is run it appears the command is 'ignored'.

Any ideas as to what is happening?  Anyone come across a 'refresh screen' command ( not a take sweep )?

Unfortunately I don't have access to an analyser normally - I'm doing what I can off site and occasional visits.
