N8262A P-Series Modular Power Meter Firmware Revision History ------------------------------------------------------------- Release A.06.03 (1-Oct-2020): Enhancements: - Solved issue of CCDF returning wrong average power measurement and NAN values when query for CCDF table data. - Solved issue of channel B showing offset of -0.19dBm when measuring 0dBm, even after doing calibration for 848x sensor with D-type linearity correction table selected. - Solved issue where zero value is overridden after a state recall - Solved issue of CCDF gauss trace query bit - Solved issue where "syst:persona:manufacturer?" is returning empty string - Solved issue of CCDF Marker movement using SCPI along Y-axis Release A.06.02 (5-Apr-2019): - Added new ccdf scpi to allow user to restart the ccdf measurement: PSTatistic[1]|2:CCDF:RESTart. Bugs fixed: - Solved issue of intermittent selftest fan failure Release A.05.09 (16-Aug-2016): Enhancements: - Added SCPI command to allow a Keysight product to identify as a legacy Agilent product - Changed *IDN query to return desired manufacturer string and model string - Keysight rebranding: - Default hostname changed to keysight format - New vendor ID for Keyishgt’s USB - Webpage rebranded Bugs fixed: - Solved issue of remote GUI hang when running selftest - Solved CAL:AUTO not working via remote programming - Solved NEGATIVE/POSITIVE edge trigger is not working when trigger source is INT1/INT2 - Solved setting average count to MAX/MIN/DEF does note turn off automatic averaging - Solved issue of STAT:OPER:TRIG:COND not reflected correctly after exiting from wait-for-trigger state - Solved different error message returned with LAN socket interface Release A.05.08 (27-Jan-2016): Enhancements: - 848x series power sensor linearity improvement - Background debug task turned off by default - Added SCPI command to query power pointed by markers in trace mode Bugs fixed: - Solved save/recall perpetual state settings - Solved gates/markets stuck issue - Solved trace display X scale issue with SCPI command Release A.05.06 (5-Sept-2013): Enhancement: - Added Run/Stop indication in CCDF table - Added QR code linking to learnware support Bugs fixed: - Resolved power drop issue while performing frequency sweep measurement - Resolved display issue of having two fields hightlighted at once in state save/ recall menu - Allows changing of trace display from window size to full screen using SCPI command - Allows user to get out of CCDF trace display using SCPI command - Resolved E9300H/ 1H high offset error upon 0dBm calibration - Resolved N1913A TCP socket connection issue - Enable TCP Keep alive value option - Resolved issue of unable to accept new connection after many LAN restart - Resolved trace jitter with EXT trigger Release A.05.05 (12-Nov-2012): Enhancement: - Added ability to change telnet port number via new diag:DIAG:SYSTem:COMM:TELNet:PORT - Default is 23 upon power up. The port number configured using this diag will not be affected by SYST:PRES DEF or *RST. Upon invoking the above diag, network will be restarted to reconfigure to the new telnet port. The process of restarting network will take approximately 20 seconds. - Implemented long sensor cable support - Enhance the CCDF trace setting recall upon preset or power cycle Bugs fixed: - Resolved trace display frozen - Resolved improper power conversion for Y scale under Trace display mode - Resolved E4412A sensor error measurement after zero and calibration with power reference on Release A.05.04 (2-Mar-2011) Enhancement: - Add new flash file system to provide compatibility on the new processor board (P1002). - New preset for LTE. - Compatible with N8480 power sensors including Q band, R band, B model and H model. - Enable external triggering in Peak measurement mode. - Compatible with N8480 power sensors including CFT option. - Enable hardware triggering for average power measurement * Enable external triggering in CW measurement mode * FW implementation to meet the 2048 buffer size memory requirement to store the measured readings up to 2048 * Assertion of external event through TRIG OUT upon measurement completion by handshaking with the synthesizer * Enable SCPI commands to set the start frequency and an auto frequency step, then enable the meter to step to new freq for each external trigger and returns corrected power readings (user will not need to do the correction at the external PC) - CCDF graphical display for complex digital modulations - Backward compatibility with E932x power sensors - Preset wireless format: WiMAX, HSDPA, DME and DME P-TMP - Minimum power measurement capability - Enhancement of Radar/Pulse measurement - Auto scale and auto gate to fit the pulse to screen - Duty cycle display for pulse measurement Bugs fixed: - Resolved linearity type selection inconsistency. - Resolved missing trigger output signal in fast mode. - Resolved measurement inaccuracy for GSM signal. - Resolved issue where inaccurate average power measurement is obtained when power/frequency sweep in FAST mode and hardware triggering is used - Resolved negative slope trigger - Resolved inconsistent rise and fall time measurements. - Resolved self-test failure on calibrator Release A.02.00 (18-Apr-2007): ----------------------------- Initial release.
