Version Upgrade History

V1.14 (December 2021) Newest Version
Fixed bugs:

1. Fixed the problem that the Model E of equivalent circuit analysis, when the frequency type of electromechanical coupling coefficient is fr-fa and the phase is not zero-crossed, the analysis does not work properly.
2. Fixed a problem in which the EOM(INDEX) signal was not output as a pulse when the EOM setting was pulse in the I/O signal and an error occurred in the contact check before measurement.
3. Fixed a problem in which the EOM(INDEX) signal was not output as a pulse when the EOM setting in the I/O signal was pulse and an error occurred in battery measurement.
1. Changed so that when the response data is larger than the send buffer size, the MAV bit is set to 1 when the buffer is full.

V1.13 (December 2020)
Fixed bug
1. Fixed a problem that GPIB communication does not return a response in rare cases when it is received immediately after sending *ESR?, :ESR0?, :ESR1?, :ESR2?, :ESR3.

V1.12 (August 2020)
Improved Functions:
1. Added :TRIGger:DELAy and :TRIGger:DELAy? commands compatible with the 3532-50.
2. Modified the small bug.

V1.11 (April 2020) 
Improved Functions:
1. Added support for the use of the control characters LF as a command terminator.

V1.10 (August 2017)
Repaired bug
・Variations in measured values may increase.

V1.09 (January 2017)
 Fixed bugs
・During USB communications with a computer running Window 8, Window 8.1, or Windows 10, the instrument sent back two responses.

V1.08 (April 2016)
1. Fixed bug that While setting to Internal trigger and measuring continuously, send a query command continuously by GP-IB I/F, measuring rarely stops. 

V1.07 (January 2015)
1. Fixed the drawing outside the display range which occurred when the sweep range and sweep point are set at the same point.
2. Fixed the bug that when saving data as a text file (CSV file) to a USB flash drive, which instrument might get hung up.
3. Fixed the unreflected interface setting which occurred when loading settings from USB flash drive.
4. Fixed the measurement value to positive value which occurred when DC resistance measurement is performed by OPEN correction value by high resister or SHORT correction value by low resister. 

V1.06 (August 2013)
1.Fixed a bug that sometimes the instrument get hung up when using the LAN interface.
2.Fixed a bug that the instrument can’t accept the connection when the instrument is disconnected during communication of LAN. 

V1.05 (July 2013)
1.Conductivity and Dielectric constant are corrected.Value had become 1/1000 times. 

V1.02 (November 2012)
1.Processing of the communication command which returns resonance/antiresonant frequency, and the communication command which returns local extreme value frequency and measured values are corrected.
2.The drawing portion of the analysis result in the equivalent circuit model of electronic components is corrected. 

V1.01 (August 2012)
