Frequency
Range:
33.0 MHz to 3.0000 GHz (2
MHz to 3.33 GHz typical)
Resolution: 100 kHz
Accuracy: ± 0. 1 %
External Input Divide
The external supplied frequency can
be divided.
Divide by: (1), 2, 4, 8, 16, 32, and 64.
The internal available frequency has
to be
³33 MHz to ensure that all
specifications are met.
The instrument will perform all
functions down to 3 MHz, except the
functions of the PULSE/DATA/
CHANNEL2.
External Input
Range:
33 MHz - 3 GHz
Interface: ac-coupled
Impedance: 50 W nominal
Minimum Swing
Pulse: 50% duty cycle, 300 mV,
tr < 3 ns
Sine: 0 dBm
Maximum amplitude: 3 Vpp, + 20 Vdc
PULSE CHANNEL 1
Delay
Delay has no period limitations.
Fixed delay between TRIGGER
Output to CHANNEL 1 Outputs: 18.8
ns nominal for trigger output divide
by 1
PULSE/DATA CHANNEL 2
(# 002)
Delay
Fixed delay from TRIGGER Output
to CHANNEL 2 Outputs.
Trigger on pulse: 18.8ns nominal
for trigger output divide by 1
Trigger on Bit 0 : - 2.0 ns before Bit 0
nominal
Data
Selects Data mode. Further selection
between 32bit programmable data or
PRBS is required.
Divide
In Square mode the frequency of
CHANNEL 2 can be divided. Divide
by: (1), 2, 4, 8, 16, 32
To meet all timing specifications, the
internal (CHANNEL 2) frequency has
to be
³ 33 MHz.
32 BIT
32 bit of programmable data are
selectable.
PRBS
PRBS: 2 23 -1 ,CCITT 0.151Norm
RZ / NRZ
Sets 32 bit data to Return To Zero/
Non Return to Zero mode.
RZ fixed duty cycle: 50% nominal
PULSE CHANNEL 2
(# 003)
Divide
In Pulse and Square modes, the fre-
quency of Channel 2 can be divided
by 2, 4, 8, 16, 32 or 64.
The minimum Channel 2 frequency is
1 MHz.
The output voltage can be set in
amplitude/offset or high-/low level
mode. Levels double when driving
into open circuits.
Limit
Maximum high and low levels into 50
W can be limited to protect the device
under test. Pushing the limit key
declares present levels as limits
which then cannot be exceeded as
long as this mode is active.
Complement (not #002 PULSE/ DATA
CHANNEL 2)
Normal/complement selectable
Data (only #002 PULSE/DATA
CHANNEL2)
Provides logical complement of data
Disable
Relays connect/disconnect outputs
Connector Type
SMA (f) for all outputs and inputs
