Frequency reading on x-axis - E5061B Network Analyzer
Hi
I am trying to automate the E5061B Network Analyzer with labview programming. I am using the instrument drivers that the National Instruments provide. I set the Number of Measurement Points to 1600, START frequency 1595 MHz and Stop Frequency 1900 MHz. Instead of getting START and STOP frequency range on x-axis, I am getting the number of measurement points on x-axis as a scale. Can someone help me why am I not getting the start and stop frequencies on x-axis? I have attached the labview program.
Also, I want to use the .vi to set the power settings to 0 dBm but whenever I use that .vi it gives me an error of 'Undefined Header'. For now, I removed that .vi from my programming. Can someone explain me why am I getting this error? I tried to find in the manual but no success.
Thanks

CRIO 9012 IP Address change
Dear All,
I hope you are safe in COVID-19 condition .
I have a question , actually we have a CRIO-9012 in a oil flow measurement that due to the high temperature ,it failed and I can not connect to it via Ethernet cable by laptop. Its IP address has changed automatically from static IP to another IP under DHCP.
I tried to change its IP address via NI MAX and give static IP address ,but after restarting the controller (CRIO-9012), it goes back to previous IP address I mean the DHCP one. Any Idea why I can not change the IP address , even I put the " IP Reset " Dip Switch to ON and Press Reset, but after restart the controller ,again it has the same IP address under DHCP . Would you please help in this regard,Any similar experiences ,any guess , any solution or Idea ?
I have attached excel files with photos for more explanation.
Appropriate your help

Labview Mobus Communication Error 56
Hello,
I am attempting to communicate with a multi-function transducer using Labview's Modbus library. I initialize the Serial Master without error and receive a blinking green LED on the multi-function transducer once the Read Input Registers.VI has begun (verifies communication has started). However, Read ADU Packet.vi errors out (Error Code 56) before I can receive register values back from the transducer. I have attempted lengthening the timeout, and get the same Error from Read ADU Packet.vi.......Can anyone please offer some assistance? The Modbus register addresses for the multi-function transducer are given in Hex, so I have converted to decimal. For simplicity, I am just attempting to read the Phase A Voltage register in this example. VI, Modbus Protocol for the multi-function transducer, and error code are attached. PN for the multi-function transducer is CRD5110-150-25M.
Thank you!

How to read data as long as there is new data in buffer?
Hello
I'm working on controlling keithley2400 to measure the I-V character.
The test need receive a lot of data.
Now,my way todo this is to set a delay time .
When I send all my orders to 2400,delay 10000ms,then it begin to measure.
I think the measure way is not convenient.
(Qt 5,VISA)
In the past measure I use readyread signal which is a signal in QSerialPort ...That's is conveniet but it does't support GPIB or others.
Thanks for all.

Trying to use a Serial - USB adapter to interact with instrument
Hi there!
I'm pretty new to Labview and I am trying to see if I can use it to interact with one of my instruments in my lab.
I have this device with a serial port that - in theory - can be used to control it remotely (give commands and read data). The instruction manual shows the example of using Hyperterminal to perform the remote operations, but nothing more. I attached an extract from it with the protocol info, to help whomever is reading this.
I read online that you can use a USB - Serial adapter with Labview, together with the VISA drivers, to perform the same tasks. I tried to put together a VI (which I attached to this post) but as I "write" something, I don't see anything coming out in the "read".
What am I doing wrong? I'd like to learn more about this!
Thanks a bunch!

Data monitor application using GPIB-USB-HS+
Please tell me about creating an application that monitors GPIB control command communication from a PC to a measuring instrument.(I want to create an application like NI GPIB analyzer)
1. Do I need to set the NI-driver(NI-488.2, NI-VISA) differently from normal GIPB communication to use it as a communication monitor?
2. If the communication monitor-specific settings are required, how can I set the NI driver (NI-488.2, NI-VISA) to control the GPIB-USB-HS+ in monitor mode?
If possible, show me the sample code.
The development language is C# and OS is Windows 10(64).
I am at a level where I can create a simple application that uses GPIB-USB-HS+ to control measuring instruments.
Best regards.
PCから測定機へのGPIB制御コマンド通信をモニタするアプリケーションの作成について教えてください。
（NI社のGPIBアナライザのようなアプリケーションを作成したい）
1.通信モニタとして使用するには、NIドライバに対し通常のGIPB通信とは別の設定が必要でしょうか？
2.通信モニタ専用の設定が必要な場合、GPIB-USB-HS+ をモニタモードで制御するための、NIドライバ(NI-488.2,NI-VISA)の設定方法を教えてください。
もし可能であれば、サンプルコードを見せてください。
開発言語はＣ＃、OＳはWindows10(64)です。
私はGPIB-USB-HS+を使用し測定機器を制御する簡単なアプリケーションであれば作成することができるレベルです。
よろしくお願いします。

Linux OS and PPS
Hello,
I want my Linux Kernel/Controller to be precision time synched to a 1 PPS. I know with the NI-Sync API and the 6674T timing card, I can send a 1 PPS signal to the controller via a trigger.
Is there any way via chrony for it to take that signal and sync to it? Im trying to get high fidelity accuracy on my Linux Controller. I see in chrony you can specify a PPS in its /etc/chrony.conf, but I'm not sure what its path is.
Any help would be appreciated.

GPIB-ENET/1000 and 100 compatibility
Hi,
I will be using a GPIB-ENET/1000 controller to perform remote control and monitoring of some test equipment. Long lead times and our archaic purchasing procedure mean that I won't get the controller anytime soon; however, I do have some older GPIB-ENET/100 units available.
Speed is not a concern so I believe in that regard the 100 should be more than adequate for my needs, but my question is when I receive the 1000, will any code I design using the 100 work with the 1000?
