How can I test a MOSFET for On-State Drain Current on my curve tracer? On-State Drain Current - ID(on)What It Is:On-state drain current is ID with a specified VGS to bias the device to the on-state. The measurement is made in the ohmic (i.e. linear) region of the device.On the curve tracer the Collector Supply drives...	835676
How can I test a MOSFET for Transconductance (gFS) and Forward Admittance on my curve tracer? Transconductance (gFS) and Forward Admittance What It Is:Transconductance is the ratio of ID to VGS. The I/V ratio is commonly referred to as gain.On the curve tracer, the Collector Supply drives the drain and the Step Generator drives the gate....	835677
How can I test a MOSFET for Zero Gate Voltage Drain Current on my curve tracer? Zero Gate Voltage Drain Current - IDSSWhat It Is:Zero gate voltage drain current is the ID that flows when VGS=0. It’s the on-state current in a depletion mode MOSFET and the off-state current in an enhancement mode MOSFET.On the curve tracer, the...	835678
How can I view the results files I save on my YBA250? These files end in .a02+ .a03 or .a05 and are not readable by my picture viewer. Results files are only viewable by being recalled to the YBA250 itself, or you can download the Virtual YBA250 program for your PC. It is on the Tektronix software downloads page and is called YBA250PC. With this program running on your PC you can...	835679

Results files are only viewable by being recalled to the YBT250 itself, or you can download the Virtual YBT250 program for your PC. It is on the Tektronix software downloads page and is called YBT250PC. With this program running on your PC you can...	835680
How do I change my 100 MHz/div+ (1000 MHz full span) on my 1705A There are 4 locations for jumpers on the Main Board (A3) in the 1705A.Strap across these pins with jumpers for a 500 MHz full span (50 MHz/div).J3J100J101J300 This FAQ applies to: 1705A	835681
How do I change the TekVisa timeout value? The timeout value can be changed by editing the VISA attribute VI_ATTR_TMO_VALUE and setting it to the appropriate value.	835682
How do I check for errors when I program my oscilloscope? When done retrieving the data, check for errors. This will let you know if the acquisition actually worked.Typical error handling involves testing the status registers. To do this, have your program send the scope an “*esr?” query. If the program...	835683
How do I check the IP address of my TLA (or any Windows 2000/XP computer)? In Windows 2000 or Windows XP click on the "Start" button and select "Run". Type "cmd" in the box and click "Ok". At the prompt, type "ipconfig" and press "Enter". It will now show you the IP address. This FAQ applies to: TLA714, TLA721, TLA601, TLA602, TLA603, TLA604, TLA611, TLA612, TLA613, TLA614, TLA621, TLA622, TLA623, TLA624, TLA7Q4, TLA7AB4, TLA7N1, TLA7N2, TLA7N3, TLA7N4, TLA7P2, TLA7P4, TLA7Q2, TLA7AA1, TLA7AA2, TLA7AA3, TLA7AA4, TLA7AB2, TLA7L1, TLA7L2, TLA7L3, TLA7L4, TLA7M1, TLA7M2, TLA7M3, TLA7M4, TLA5201, TLA5202, TLA5203, TLA5204, TLA5201B, TLA5202B, TLA5203B, TLA5204B, TLA7NA1, TLA7NA2, TLA7NA3, TLA7NA4, TLA7012, TLA7016	835684
