Section Specifications
Page 2-l. add below first paragraph:
“‘No Warning’ adjustment range: this term is used in the specifications to define the range of
adjustment permitted by the firmware. when this range is less than the hardware specification.
As
explained at the beginning of the Operating Reference section (as modified by this Manual
Change!) the hardware specifications can be fully exploited by overiding the firmware limit
with the shift key.”
Page 2-4. Output Amplitude
Headline “Range” add:
“subject to the duty cycle setting (or the ratio of the pulse width and period settings), see
Figure 2-1 on page 2-7.”
Headline “Current” change text to:
“20
to 1 A (50 ohm into 50 ohm), up to 2 A into short. 40
to 2 A (Hi-Z into 50 ohm.”
Page 2-5, Source Impedance
1. Change
kohm” to 1 kohm”
2. Add new line “If Option 001 is fitted, High Impedance can only be selected when the
baseline is set to zero”
Page
Pulse Performance
change to read:
5% of amplitude
Page 2-5, Pulse Performance, Settling Time: change text to:
ns typical. This means, for pulses
ns wide, the amplitude specification is modified
by the overshoot and ringing specification, i.e., effectively:
of amp/-150
Page 2-6. Width.
Substitute the text under “Range” with:
For output amplitudes up to 20 V: 10 ns to period -10 ns. For output amplitudes
V: 10
ns to maximum shown in Figure 6-l
Hi-Z source resistance, the minimum pulse width
is typically 20 ns, the maximum is typically period 20 ns.
No warning’ adjustment range:
ns to at least 90.5% of period (95% with periods
us).
Page 2-7, Duty cycle.
Headline “Duty-cycle”, replace text with:
“The Duty Cycle parameter sets the pulse width as a percentage of period instead of an
absolute value.
Range: Limits as width specification.
Resolution: 0.1% of period.”
